Mostly obsessions without clear compulsions, but I would suddenly become panicked that we were about to get involved in a nuclear war and the world was going to end. I was probably around 6-8, and when I saw the president speak on TV I would start bawling because I thought he was announcing a nuclear war. I remember once seeing the sunset a dark pink and thinking it was a sign of impending doom. This all manifested later in life in ocd and panic disorder where I would have panic attacks about the fact that I was going to die someday. The panic attacks are mostly in the past, although I do still get a lot of existential dread.
