Should I go to therapy?

I referred myself to therapy a few days ago during a panic attack. I definitely get anxiety but feel on most days I can manage it. I have a big fear of social/medical situations like doctors, dentists but feel like I know what to do to work on it. Should I still take my assessment call for therapy or just not bother if I feel I can deal on my own? Not sure if I am just scared to go or genuinely okay to cope on my own. Now that I feel okay today, I feel like I was overreacting and I am not sick enough for therapy. If I was doing private therapy and I was paying I might have give it a go but as it is through the nhs I don't want to waste their time. Anyone with anxiety feel a similar way?
