Hi,
I went through a similar problems.. youngest is 14 months and I want to go back to doing a degree. However I have no more years left as I have also dropped out twice due to pregnancies, domestic violence, family court etc and of recent debt problems. I’m currently suffering depression and anxiety. So I totally understand.
best advise would be speak to SFE
you have to write a detailed letter explaining what you had experienced and any evidence backing this up: crime reference numbers, supporting letters some services you have accessed, child birth certificate. SFE can give you more detail on this.
in terms of courses; many universities have access courses; year 0, some even have an evening class you attend 1 day a week (say for 6weeks). Mature students trying to get back into education.
Hope that helps and if you have any questions- I’m more than happy to answer x
