I feel like every time someone compliments me, or is even slightly nice to me, they lie or do it because they pity / feel sorry for me. 

Like now for exemple, I do a creative writing course, and I only got positive feedback, and instead of thinking that I actually did a good job, I immediately think it’s because people think I’m to fragile to be criticised.  When I meet new people and they try to be my friends and want to talk to me, I too feel like they don’t really like me or think I’m actually interesting, but just feel sorry for me or infantise me. It’s so weird. How do I overcome this? 

(I have ptsd maybe that’s why I can’t believe someone would actually like me or be interested in what I have to say but it’s really really frustrating).
