I spent most of my 20s working admin jobs in different settings (veterinary receptionist, exans officer in a college, library assistant, executive assistant in the charity sector).
I went to uni in the evenings in my mid-late 20s starting with a CertHE - initially planned to apply to vet school but after lots of work experiences and thought turned down my interviews as I didn't think I'd cope (history of depression and anxiety combined with a career with a very high suicide rate seemed like a bad idea).
I got high marks and moved from the CertHE to y2 of a biomed degree. Got a 1st class hons & secured a place on a scheme to train as an accountant in the public sector.
I hate it. I like most of the day to day work of my postings but the courses (ICAEW ACA) are so so dry. I'm scraping passes and really struggling to concentrate. I'm also pregnant which hasn't helped as I'm exhausted. I'm scared I'll fail. I'm also scared I'll somehow qualify then make a catastrophic mistake.
I just don't think I'll ever find a career I'm good at. I'm not stupid, I usually pick things up quickly but I just feel like a total failure.
