Hi and welcome, lovely. I didn’t get past A levels because I had a breakdown at 16, and realised that trying to do uni would risk another crisis. I have since gone to night school to do an HNC in Business and Finance, qualified as a reflexologist, and am currently studying theology (working from home). I took the decision to see my education as a hobby rather than a means to work - which makes it much more enjoyable and less stressful.
You’re putting a lot of pressure on yourself by looking at what you ‘should’ have done. What is it that you ‘want’ to do?
