Young, Dumb, Young Dumb and Broke.

Dude. If you got into college you aren't dumb, and the good job may help your mood (as my husband says, money doesn't buy happiness but sure removes a lot of the stresses and lacks that cause sadness.)

My best wishes to you, and also to that weird vegan who is in a similar situation. I can't say things will get better but will say things CAN get better.
