I get really homesick too...and I get intensely lonely when I'm away from my SO for even a short amount of time, though I try not to let it show.

I've been there...it sucks. Honestly, I was miserable through most of my school life until my sophomore year when I took my state proficiency exam and graduated early. I remember enering a charity run at school once. I earned a lot of money for the charity but it didn't matter because I was the last person to finish the run and that's all anyone remembered. Gawds, it still hurts....

Honestly, my way of dealing with things was to bury myself in books. Novels, textbooks, comics, whatever...just anything to escape reality for a bit. I think this benefitted me in the long run because I learned a LOT in those years, but I wish there had been an easier way to handle it.

If you want, drop me a PM, I'm always willing to lend an ear.
