I have to agree with the general sentiment of the thread here. I was in your shoes this time last year, actually. I was one-hundred percent ready to mentor a team in the city I went to my freshman year of college. Heck, I even scheduled my spring semester classes so I wouldn't have classes that required attendance Thursday and Friday.
By the time build season rolled around, I had so many other things to do (responsibilities! activisim! 2am pizza! HOMEWORK) that mentoring was at the very back of my mind. It's also of note to mention I wouldn't have done the above things if I was mentoring in some capacity - I may have a different way of doing things than you.
I decided to volunteer instead when a regional came to the city I was in. During competition season, I'd watch a few regionals while doing my homework. It was an easy decision for me to make because I had already volunteered my senior year of high school and knew the VIMS process. I also really enjoyed volunteering. It might not be an easy one for you, maybe because this may be your first time volunteering. Looking at your location, there may be an off-season event in NC that you could go to.
There's nothing wrong with wanting to mentor a team, even your own team, straight out of high school, but that isn't to say it will be as easy as jumping back in where you left off with your old team. My older brother ended up going back to our old team, but limited himself for a few weeks when he had school off. That way, he knew he would not fall behind on his schoolwork - which happens a lot in college. The transition was also easier for him because he was a team captain when he graduated. If you do want mentoring resources, I'd go on
NEMO.
I know someone already asked, but have you considered mentoring a team on the jr.FLL/FLL/FTC level?
Either way, I wish you the best, and will be here for advice. If it becomes overwhelming, there's nothing wrong with stopping and taking time for yourself.
