that's really horrible of him. I'm sorry you were simply dismissed when you were looking for help. I don't see how the mental health support and the abortion need to be mutually exclusive. I know if I were in that same position, I would be talking to my therapist about it at the same time as discussing other things. I know the healthcare system works differently over there, but no one should ever be turned away from support. also, don't mh referrals take quite a while over there? I would think he would want you started at least on th einterview process and get the paperwork going so that, even if it doesn't start before the abortion needs to take place, at least it can get rolling shortly afterwards. Would they do the same if you were deciding on cancer treatment and getting connected with mental health services?
If things don't go as planned with your uni GP, can you just go to an emergency room to get some help? From my understanding, it's a lot more difficult to get commited over there (more options for talking your way out of it), and maybe they can also help with the abortion issue?
Good luck with everything... (oh, and totally don't go back to your old GP... apparently he sucks).
