I have a degree already and worked in a field vaguely related to that degree. However I had to leave my old job due to very poor mental and physical health. I eventually found my current job and really enjoy it. I feel it's something I'm good at, it doesn't effect my health anywhere near as much and I find it interesting. I only work part time at the moment but feel confident my health would be okay if I went full time if a job came up / I went back to university. The only way I can progress is by going back to university. I've looked into other options for progressing but there just aren't any. My earning potential without university is very limited.
Going back to university would mean a drop in income by quite a bit throughout my time there but I know after graduating I'd then be earning a lot more than I currently do (plus hopefully I'd also be on a full time wage too). DP and I have discussed this extensively and we could financially manage but it would mean that chances are we won't be able to take 7 year old DSD on holiday until I graduate/ start earning again. We currently do 2, possibly 3 UK trips away with her at the moment but that would have to drop to none. We've thought about me going next year instead to save up the money but I have a place for this year and there's no guarantee I'd be allowed to defer or be accepted again next year if I reapplied.
AIBU to go anyway even though it means a pretty miserable childhood for DSD for the next 3 years?
