I'm gonna get straight to the point - I have had an insane anxiety regarding pregnancy ever since I started dating my boyfriend. Logically, I know that nothing we ever do together can cause a pregnancy (for example him fingering me or eating me out, and me jerking him off or giving him head), but whenever my period is even a tiny bit late, my brain seems to freak out, ignore all rational thinking, and skip straight to anxious thoughts like "oh my god what if I'm magically the only person ever who gets pregnant from this". I know this sounds stupid, but at this point no matter what I do, my brain eventually causes me to get insanely anxious, and sometimes I even end up starving myself (because I also wanna starve the potential fetus and make it die).
Is there anything I can do to get rid of this / manage my anxiety a little bit?
PS.: I'm gonna start going to therapy in the summer (there's a new free therapy service for teens in my town, where you can go to a licensed therapist anonymously without your parents or anyone knowing, which I think is really neat!!
