Hi, this is OP! I'm not doing the whole partying and not giving a crap part because I've already done that when I was their age so now that I'm older I'm more focused on the important stuff like getting a degree. Still, I underdtand where they are coming from, I was also like them when I was 19. Also, I am working as a freelancer on the Internet 30+hr/week so I'm way too busy and tired to get wild! The reason I think the other students don't like me (there are exceptions, of course) is because I really found myself in the field I'm studying now and like to participate in class discussions with questions and my opinions. Also, since I'm older I'm not that intimidated with my professors so I have a more friendly (but still respectful) relationship with them and they like me for my curiosity and interest. Maybe the class think that I'm a smartass or something. But I am super grateful for your support especially now when I'm tired and frustrated with it all and I will keep going for my own well being :)
