Dealing with Guilt and Intrusive Thoughts

I also feel constant guilt all the time and its draining. As a result I overapologize and recently these people kept making fun about it, so it's hard having friendships when you're being judged by them. And they don't understand your behaviors.

Yes frequently. It's rough to always feel guilt about things that you had nothing to do with or couldn't control. I still feel guilty from a friend in college dying but she was epileptic and have a severe seizure. It isn't my fault but I feel like it is.
