Is your child a daughter or a son? When you say close - how close? Do you do a lot together? How far away is the college? Do you have cell phones? Will your youngster compete in athletic or other events that you can attend?
Our middle daughter is attending Meredith College (a women's college) about an hour away from us. There are programs' available for the Mom's (and some for Dad's) that allow you to be involved with the students and/or you daughter. Our daughter and I chose not to do this - I didn't really have the time and she wanted a chance to spread her wings a bit. She's still very involved at home - coming home on some weekends and on all school breaks. She's not a partier and when at home on extended breaks, has a part or full time job. For her first two years at school - she didn't work nor did she have her own car and was VERY involved in extra curricular programs in the College (karate, performing w/ aquabatics ? swimteam, performing in plays, managing the costume shop - she's a theatre major). Now she's living with her fiancé and may be getting both a car and keeping the job she started this summer - we'll see.
Me - I seemed to be VERY different... After having the full care of all three often by myself while my hubby was active duty and then as a civilian that was overseas w/o his family, I have enjoyed "my" freedom from some of the care and responsibility. I was able to maintain doing some things with each of our daughters, but not anywhere near what we had when they were at home. We all enjoy it that way!
Our oldest lived at home while she was going thru a local community school program, moved out when she was pregnant and first had her daughter and then moved back in with the baby and her boyfriend (that was rough - 'nuff said). They were able to get their own place and that was better for all involved - though, in a bad situation, we'd still take them back in.
Our youngest started going to ITT for Electronics Engineering (computer) the day after she graduated High School while living at home. Then she found a job - a good one! - not far from where she was attending school and an apartment opened up that she was able to take over the lease on. She moved out - at the youngest age of 17. Due to her schedule - we rarely saw her and had little to no inkling that she was having major problems w/ the lease (I had worried, but hubby and daughter assured me everything was good - he saw her more than I did as her school and work was on the way to/from work for him). She came to me recently, just about in tears, and asked if she could move back in. The room mate "thing" hadn't worked out and she simply couldn't afford the rent along with the payments on her new SUV (new to her) and insurance/gas and had gotten behind and was being evicted... She was heartbroken and is still feeling like a failure but doing better. She's finished paying off the rent she'd been behind on, gotten a couple of other bills caught up and is now paying us rent plus occasionally helping out with the ponies again feeding & training (can't count on it, though). She graduated in June with honors and then moved up in the company - getting a permanent position with larger pay and more in line with what she was studying. She has learned, the hard way, that a vehicle needs to be maintained when she had a blow out on a major interstate July 4th weekend. We took care of the original problem, she's since gotten the other tires replaced and some other work done on her vehicle that needed attending and is getting the spare replaced this week. She starts paying for her school loans soon...
But they each return home - for family gatherings. Sometimes, they spend time with me with the ponies - but none has ever had the fascination that I do with everything equine. Don't know that any could set up and follow a feeding program on their own nor consistently train one that isn't already started. BUT they each are willing to step in and help out. They share interests with their father too, that has nothing to do with the ponies.
It's a relationship that works for all of us. Yes, at times I really miss them. But they are all three developing into beautiful young ladies and adults - inside and out - that we are both proud of. They are very active on FB (ick), and they are willing to keep in touch via phone calls and texting and we also get together with them. I've had a GREAT time going to places with the ponies and DO wish that the girls still came with me. My hubby and I were able to comfortably leave for 5 wonderful days by ourselves in Florida for our 25th wedding anniversary in June - the youngest stayed and cared for the animals inside, the oldest checked in, a friend took care of the ponies. As they've grown up, I've been able to go from being a stay at home mom, to working part time to working full time and back to working part time (& was laid off last fall, doing job interviews again now). My hubby and I enjoy watching a movie now and then that doesn't have to be "agreed upon" by everyone! We like our newly found shared time and are exploring a completely new relationship. At the same time, sometimes it DOES feel like I'm rattling around in a small but echoingly "empty" house...
Maybe you could discuss with yours how you feel? If your child allows you to - be involved with helping pick out some of the furnishing for the dorm room. Arrange time to get together and then ... take on something that is totally different from what you did with your youngster. OR if you really want to still be involved - get involved (or stay involved?) with the High School - the Drama Club, the JROTC program, Band, FFA or wherever they may need help, parental support. It's amazing how fulfilling that can be FOR YOU. And don't forget that you have other family members at home - sometimes that reduces some of the stress of the one that is leaving...
WOW, I've just given a huge & personal synopsis of our lives.... Hope it isn't TMI and that it helps out in your situation!!!
