What do you do when you have made a new friend who tellsyou that they have been hurt by people and they have trust issues and they make you feel as though you have to validate everything you say to them?

I have made a new friend and I really want this friendship to grow. I am starting to feel as though I am being put under a microscope with her asking me the same questions and Im getting a strong feeling she doesnt believe what I say sometimes. It really got to me last night when we were chatting (on the chat section) of Facebook and she asking questions about something sensitive in my past. When I would answer she would respond with ‘ic’ and ‘arh’. I’m just wondering if anyone else thinks that sounds like someone is being sarcastic or am I just overly sensitive. I ended up saying something abrupt and she just logged off immediatley. Now I feel aweful, but Im tired of feeling like someone thinks Im lying. There is more to this but too much to type. Thanks for any insight!
