Hi Sunbury and welcome
You didnt give me much to go on so please excuse me if I say things you already know or are already doing.
PTSD is a hard road to travel - I know for me that things only started to get better when I went to see a psychologist - are you seeing one? if you can't bring yourself to go into their office then if you explained they may be able to do a phone session to get you started (although it is better if they can see you - but we do what we can when we can)
I hope you have family and friends to support you (we can offer support here too if you need it and can tell you what worked for us ) In the beginning I found talking about it the hardest thing to do - although it was constantly running like a tape in my head - my psychologist helped me work out a lot of things - I'm still working on it but there is hope.
I hope you will let us know how you are doing - take care MBC
p.s., a psychologist or counciller may also be able to help you with your fear of dr's.
