Stay with your old roomies until you get better.
Why are you doing so poorly in school? Not studing? Partying too much, Sleeping too much? Skipping classes? Not doing the work? Why the bad grades? It' sounds like it's time for a little "Come to Jesus meeting " with your parents. Your grades suck, you got kicked out of the dorm because your grades suck, you've been breaking the rulles by staying with your old roomies - which puts them at risk too. I willing to bet you don't really care about rules or consequences anyway, or what happens to anyone, even yourslf, - you just do what you feel, when you feel like it.
So like I said - I think it's time for a little meeting with Mummy & Da. You need to be straight with them for once and tell them what you've been up to, and then save them from shelling out any more of their hard earned money, money that you're just wasting. I'm not saying you're stupid, but you sure sound like your not interested, or at the very least not ready yet for another 5+ years of school. It sounds like you need to get a job, and get your own apartment, and do some much needed growing up..
Listen, I'm not trying to insult you, I think I understand a little bit of what you might be going through. When I finished HS, I worked construction for the summer, then went to college. I dropped out and joined the Marines at 17. I spent more than 2 tours of duty in Viet Nam before I was wounded a 2nd time, and coould not return to active duty. Once I recovered from my physical wounds, I went back to college, I made it through 1 trimester and dropped out again. College just wasn't for me . It was'nt hard, - it was borning, and it was taught by too many anti-war liberals who were more interested in challenging my being in Viet Nam than in their Class room. So I went back overseas and for the next twenty some years I worked construction all over the World..During that time, Between Viet Nam and those twenty years working all over the world, I learned more than what some college class rooms could ever have taught me about myself and life. I became fluent in several languages, learned how to inspire, train,and lead men. Learned how to plan, and execute a plan, when to stick to the plan, and when to go to a contingency plan. I I learned when to stand and fight, and when to pack it up and move off as quickly as possible.IIearned to read people, and take swift and decisive action when needed. I learned that sometimes you fight, and sometimes you compromise. Sometimes you speak up, and sometimes you shut up, but you NEVER GIVE UP.
Lastly, you need to know that YOU are the only one that can make YOU happy, sad, lonely, in love, crabby, satisfied - whatever, so never rely on others to give you your life or your will, make your own decisions.
