Lizzie, you spent many years getting to the place you are now and it's unreasonable to expect an immediate solution. I understand what you've said (below) and it's taken you a long time to get to the place that you'd ask for help but now that you're here and have a diagnosis,
"after hearing my experiences is that she's not surprised that I have little trust or faith in people"
which you agree with, you expect an immediate cure and it doesn't work that way. Look at it like this; the events affecting you began in your early teens, let's say 13 for discussion purposes, and you're 46 now. There has been 33 years (8,760 hours per year time 33 equals) 289,080 hours over which these events have occured. You've had 3 one hour sessions to correct 289,080 accumulated hours worth of problems.
May I suggest you give counselling 52 hours (1 hour per week for one year) an opportunity for you to find workable solutions to these problems. One other suggestion I'd make is group therapy. Somethimes you just can't beat sitting down with someone who had or had the same problems as you.
