Feeling so hopeless and fed up

Feeling hopeless

Hi all - I know this isn’t strictly to do with teaching but I really need some advice, suggestions and ideas. Long story short, I left teaching as a secondary English teacher is September due to stress, feeling fed up and just done with the profession. I’d heard a lot of success stories about people transitioning out of the classroom and into other roles - but it feels like some sort of myth. I have been applying for jobs since June and had interviews each month or even two a month. No success. All comes down to other candidates having more experience which really upsets me because why even interview me? I’m stuck doing supply and losing hope that I can even get a job. Has anyone had something similar? I can’t see how I’m going to continue looking for full time employment in a new sector with this feeling of hopelessness and straight up crap. I am now going on to my sixth month not having full time work and although cover is good (quite chill and pays the bills) I can’t help feeling I made the wrong decision.

Should I just go back to teaching? I’ve seen a few roles in my area but none at schools I’d particularly LOVE to work at.

I taught English for four years, was an examiner and had two TLRS in pastoral. I’ve had interviews for uni roles, post 16 roles, charity jobs and nothing works!
