Intrusive Thoughts

This is going to be a weird topic for me to discuss but I really want some advice about this. Very recently I've been worrying about being attracted to my grandpa and now I'm having horrible thoughts about harming my grandma that seem to stick and won't go away. And the past few days I have been feeling extreme anxiety and depression because I kept getting thoughts about being transgender which was triggered by watching a tv show but now those thoughts haven't been bothering me as much as the ones about my grandparents. Both seemed to come out of nowhere. I'm not sure if it's OCD or if I have a condition I don't know about but I want to start talking to a therapist but I'm scared that they'll report me for telling them this. I'm just really confused about why I've been having all these thoughts within the past couple of days and it's been really hard to concentrate and sleep and I feel more anxious than usual.
