OCD and GAD

I’ve been diagnosed with OCD and GAD. I pick my skin to cope with this sense of impending doom, then become more anxious because I’m afraid I’ll get an infection through the wound so I immediately pour hand sanitizer on it. The burning sensation provides temporary relief and it’s like I can “feel” the microbes dying? Like idk how to describe it. I also get unwarranted thoughts of self harm. I’ll randomly be like “being dead is easier” or “I don’t deserve to be alive.” I just get so overwhelmed with the future and then my brain is like “you could unalive yourself.” I know there’s some overlap between both disorders so I’m just wondering if anyone else has similar experiences? I feel like even though I have a diagnosis and am on medication and have been in CBT that something is off.
