I'm feeling really really low at the moment, and i keep breaking down. i have on various occasions tried talking to my boyfriend of 18 months about whats wrong, but i can never explain it rationally, its just everything , im under a lot of strain and facing loads of uncertainty, and he always ends up being frustrated and pissed off that i dont actually seem to be able to work out whats wrong. all i know is that i've suffered from depression before, that i'm quite negative but that i do try really hard to keep going and do things that'll make me feel better. the problem is, i keep telling him after i break down for the umpteenth time that i'll be ok and then two days after i;m a wreck again. i've now stopped even bothering telling him, he's under alot of pressure too and i dont want to add to it, but feel it's really bad for our relationship. i really really can;t talk to him about it as it;s always the same old story, i'm worrying about everything, and also things like where our relationship will go next year at uni. i used to be able to cope and pull myself out of these little bad phases but at the moment i can;t and i feel so lonely. i love him so much but i cant seem to force myself to be stable and happy, and i end up not even wanting to talk to him as i hate being fake. we always used to talk so much, but he's so focused on his studies and refuses to talk about anything serious, which i understand, but i feel we've lost what we used to have. being without him would be worse but at the moment being with him is making me so unhappy too... what to do?
