What's stopped me have been the experiences I've had in the past with other therapists/psychiatrists. It can be very difficult to find someone suitable. I've had quite a few negative experiences - plus I've had lots of hospital admissions, with more experiences. (not all bad though)
I'm just tired of it all - trying to explain everything to some guy and hoping they'll at least be polite and responsive for starters. Let alone having the skills to be able to help. Plus I hate medication which is what they always insist on for me.
