Might have obsessive compulsive disorder

hey there, I've noticed recently that I've been like super anxious/overthinking about the Simplist stuff+being extremely paranoid about stuff like:"what if someone touched my stuff while I was asleep,what if someone set up cameras in my place while I was out"... etc and it's been hell for me just earlier,I was doing something alone at home,my called me (I called her earlier,she didn't pick up) and while we were talking she made a joke about something I was doing (which I was doing) and got ultra paranoid with thoughts like (did she bug my phone,installed an app to listen on me...etc) any solutions? a psychiatrist? a therapist? I'll take anything at this point
