Stupid panic attacks

Sometimes I think that I can't allow myself to be happy. I'm always waiting for the bad to happen, and it triggers panic attacks. I actually just had a panic attack because my son is hanging out with a friend, and I thought that my husband might not want him hanging out with this person because of certain issues. It sent me into a huge attack. Which is stupid. My husband met the friend before and is okay with him. But for some reason I freaked out.

I couldn't just sit back, relax, and know my son was having a good time hanging out. I had to make it into something negative. Exhausting. I wish my brain wouldn't do that.
