Do I need therapy

So I get really nervous for things, sometimes it’s reasonable but sometimes I’m like why are u even nervous. But when I say nervous, I feel sick to my stomach, bad belly ache, going toilet a lot.

When I look at signing up for therapy they ask questions like “do you feel suicidal”, “down and depressed”, “scared to talk to people” and I don’t, I’m confident talking to strangers and I’ve come a long way i used to be a lot worse and not do anything on their own but I’m tired of being so nervous about things all the time. I don’t want to waste a therapists time because i know people have it a lot worse but I’m sick of it and if it can help I want to do it.
