I need some advice and maybe solutions

Hello! I’m 17 and I already go to a therapist for anxiety and OCD and I feel like the wider amount of people I ask for advice may help me find other ways to improve. So in short, I keep getting thoughts of this one time I was pinned down by my uncle (I think? It’s a bit blurry) and all that I know was that after I was crying and I was pushing him away. I don’t know maybe it was because of the lack of space or control of the situation, I tend to get really anxious and even cry when I cannot control situations, whether it’s on planes or literally driving places I have to constantly check around me so I can Prepare to get hit by a car or run off the highway. I come up with numerous plans to escape school shootings without being harmed and even saving my friend, I have found out where her classes are and how I can take her and run out of there and I have been trying to get fit incase I have to fight back to protect myself and anyone I love but it is a constant thought. Another thing that comes to come constantly is the taste of my mouth, right now I ate dried strawberry’s ( I love dried fruit) and I have that lingering taste in my mouth and I want to throw up and my stomach feels still empty but I literally ate lunch already and breakfast so I wonder why sometimes I try to put salt on my tongue to make it go away but it just won’t. Another thing I am Christian so I Often pray, but when I pray I have to atleast do the cross symbol on my face 2 times, or any even number, I usually do it when I’m eating, when I wake up, when I get on the bus, when I get in my car, and when I go to sleep (4 times when I sleep, 2 times for the other times) and when I forgot I do it 8 times and sometimes I wonder if I’m doing enough, anyways that’s all I can write currently, any advice for this would be appreciated.
