The “What If” Loop

does anyone has any tips how to stop the "what if cycle"?? i have very disturbing what if thoughts on daily basis and they're rlly scary always. i know they're not real but sometimes they feel so real and possible to happen and i hate this

My OCD is continuing to have me constantly check and check and check! I keep doubting and am very confused! How can I get out of this trap!!!!!

Anyone else have repeated thoughts that play that are negative. Basically a back and forth of you telling yourself you don't want X to happen but having a thought that slips saying you do. Like being stressed out one day and saying "man I wish I were dead". But instead of letting it roll through your mind and thinking nothing of it, you obsess if you actually want that outcome for yourself and you are now scared you'd fatally harm yourself whenever you feel anxious or stressed even though you know you wouldn't. So now I repeatedly get I wanna die stuck in my head and I feel the compulsive need to say no I don't to combat the thoughts and it happens throughout the day and even when I wake up.
