Intrusive suicidal thoughts

Lately I’ve been getting a lot of intrusive suicidal thoughts. I feel like so much of the time I’m thinking “I want to die” and then I’ll be okay for a bit then I’ll remember the feeling again. Or, I’ll think about jumping my balcony or ways I could kill myself when the time comes. I’ also have this weird theory I’m going to die suicide. I don’t even know what this is. I have so many mental health issues and OCD seems to be my most prominent so I decided to post here to ask if this seems like and OCD thing or something else?
