i dont really get the "i dont want drugs" thing. god - take the drugs get feeling better!
i moved 300 miles away from my friends and family, i missed the prestige i got with my job, the contacts i know the community - i missed not being able to get away from dh after a row and just go to my nans for a moan and a cup of coffee, i missed not being able to go out with friends and get shitfaced.
i missed it all. i felt isolated and lonely - despite.....living 5 mins from the sea, the kids getting a much much better education, schools better, the health service was better by far, my dd was finally diagnosed with being partially deaf and things were moving - it alls eemed so fking perfect - i felt so terrible one day i just collapsed in front of the washing machine, curled up into a ball and stayed there for ages. that was my lowest point. i went to doctors.
the isolation lasted for about a year. my first social pissfest came with a mumsnet meet up - and i know there are mumsnettters in australia - its a big place! but worth a try.
you need a mums and toddlers group or an excersize class or a wight watchers class or an evenign class - something to get you out of the house and meeting other people - if you dont put yourself out there - no ones going to come knocking on your door and say " your fab be my bestest friend" its not going to happen.
after the mnet meet ups - dh took me to pub once every two weeks - this still stands when we arn't skint.
i reckon for you , when your kds start going to school you will meet other mums maybe become nvolved int he school ins ome way.
the horrific horrible awful truth is - only you can save yourself.
