I used to have a terrible time sleeping after my SA. There are a lot of videos that you can find on youtube to help you sleep. I suggest finding one that you like and turning down the lights and putting some head phones on and watching it until you feel sleepy or relaxed. Also things like Valerian root, and other herbal remedies work well for sleeping. Sometimes just making a sleep routine can be helpful. Like turn on a ceartin low light lamp before bed, then go brush your teeth, then read your favorite comic and listen to some music you like, etc.

I also suggest if you have a bad dream to not try and go back to sleep right away, try and get up and get out of your room fix yourself a cup of tea, and do something to distract yourself for a bit.

As for the T's just keep trying. You can always ask the once you contact for referrals to someone who might be more appropriate. And I like Growlycat's suggestion that you see what your insurance has to offer. You might also want to check and see if your insurance has an out of network benefit. If they do you might be able to see someone who is not on their list for a reduced rate (although it will not be as reduced as with the full benefit).
