I appreciate the responses and advice, it seems the main bit of advice is to significantly reduce my work hours which would indeed solve many problems.
Also, because of the long commute for uni I’ve not really made any friends, but that’s a problem to put on the back burner for now.
I worry that if I tell my manager I am unable to do so many hrs I will just get sacked, as many people before me have been sacked for less.
I guess what I need to do now is make a priorities list and figure out what I need to cut loose.
Again, thanks for the responses 👍🏼
