Cant forget about something that bothers me too much

I'm sorry if it's not allowed, just remove my post if it's not. There's something that's been bothering me a lot because it's a little scary and sort of like a "loose end." I can't make the situation better, it stays as is, kind of in the unknown. Id rather not go into details so I'm sorry if you're really confused! What do you think I should do? Talk to a counselor/therapist? I've been thinking either that or maybe a hypnotist. Can hypnotists help you forget certain things or memories? Please help 😭
