What to do when it all gets too much?

I have just moved town from Christchurch (NZ) to be with my partner. I have always had problems with depression and anxiety, but lately it's been getting on top of me. I don't have any doubts or regrets moving to be with him, infact I can't imagine life any other way. It has been a real struggle looking for a job though, and moving in with his flatmate who owns the house. She has her own ideas about how I should be job hunting, even though she has no idea about how I don't handle big things very easily. I just feel like my confidence is nearly zero and so is my motivation. I've come off anti depressants and I don't want to go back on them. The doctor I've joined up with doesn't give a **** and just sent me to a counsellor. We have booked flights to Sydney to start fresh over there but that's not for another four months. I did just get a retail job, but I was so unsettled after my first day which was today I have felt physically sick all evening. It's really hard when you don't have your own place to go back to and really relax. I want to hang on for that four months but I feel so scared of everything. My partner has been amazing but I don't want to drag him down with talking about this stuff all the time. He said he just wants me to be happy, but if I can't stick at a job we will never get to Syndey. I just don't know how to be more confident. I wish there was a switch you could just turn on!!!
