Blueeyes,
like hotasfrick I also know what you mean & I agree get rid of the people in your life who are dragging you down - but maybe first ask whether you are keeping people out. I tend to be the helper but I do not ask for or really let enyone help me so maybe I have myself to blame on that score abit at any rate.
University, work, study, boyfriend (especially moving in with another person & all the emotional baggage that involves - it's hard work) plus being away from family & all that you grew up with is a really hard time in your life - so cut yourself some slack - it is ok & normal to be scared. Plus you have maybe had others around to turn the stove off & lock up now you feel more alone (men can be pretty useless in respect to the day to day things in life like that!!) & that responsibility along with all the rest is tough.
It is important to remember that university & study is not the end of the world & if you don't do well life does go on - get things in perspective - my daughter phoned from uni today to rant about her film essay which is due in 5 weeks & the lecturer informed them today that he still hasn't decided whether to give them a list of topics or get them to decide on a topic of their own - I poiinted out that in that case she could get her other stuff sorted & then only have that to work on & asked her not to actually kill anyone just yet!! So take it easy, relax, do some fun stuff, keep perspective including klnowing that it is ok to get stressed.
Pm me if you want to talk.
