Depresssed

I am a 21 year old girl and i have just been diagonsed with depression for the second time.. The first time i had depression was when i came out of hospital for having my appendix out i was only 16 the thought of someone cutting me open just completly freaked me out.. After being in hospital i had really bad anxiety with that came bad sleeping, panic attacks, not eating, and obsessive compulsive disorder.. I went on anti depressants and all was well, i still had my OCD there but i could control it.. I recently went to the doctor the other day in a panic, cos out of the blue i started getting panic attacks again (very random) he has given me some medication to take which i have only been taking for 6 days now and it seems to be taking a while to kick in.. He said it would take about a week can it take longer though? i really want to get better its just hard when my bf and his family and my family haven't been through what i am going through now.. I recently moved to australia bout 7 months ago and am really missing home now.. I haven't made alot of friends which i think doesn't help me either.. nothing to keep my mind occupied and in a good place.. I have decided to go see a phycologist and tell them exactly what im feeling and thinking.. I know that this is going to help me but i need reassurance :s
