Scared of things multiplying

I have claustrophobia. It really is dreadful. I can’t use lifts, lock toilet doors or be anywhere that I think will be enclosed. I freaked out at the dentist because I couldn’t cope with him and the dental nurse crowding above me. He gives me sedation now. I really should seek help with it because it’s getting worse. I’ve really tried to overcome it but it’s useless!

Fears usually start in childhood imo. I don't like heights and sweat profusely if it's on TV with cliff edges. When I was 4 mum was putting out the washing chatting to a neighbour. I stood in a wide open upstairs bedroom window balancing on one leg pretending to be a ballerina. Mum told me to get down and sent our collie dog Sandy to get me down. He grabbed my flared dress and dragged me back onto the bedroom floor ripping my dress. I think this caused the phobia of heights. I don't like pitch black bedrooms either and need a dim night light to sleep. Probably because I was locked in a cupboard at 3 yrs old and fell asleep in there - not by my lovely mum I hasten to add.
So OP you are normal most people have phobias. Perhaps something happened when you were a child or you saw something that frightened you.

Have you tried Hypnotherapy?It's not an old bloke swinging a watch on a chain, it's just chat and suggestions and may be able to relieve your anxiety around heights.
