I dont know if this is the right place to post this but I'm lost for what to do

As of currently I work part time at Mc Donald's and personally I hate it. It takes a massive tole on my mental health but without a job I can't survive I've tried applying to hundreds of different jobs in my area and most of them don't even get back to me and the ones that did, didn't even allow me an interview.

A couple months ago I reduced the amount of days I worked down from 5 days to just 3 working 7 hour shifts each day but even this still hurts it alot and as a result of reducing my hours I've had less money and very generouly my partner has helped me out where needed but I don't wanna have to rely on him to help me out so I'm stuck.

I don't know whether to go back to doing 5 days but working 6 hour shifts and risk ruining my mental health (which still isn't great) even more or do I keep only working 3 days and never spend any money (which will also ruin my mental health as it'll mean I won't get to socialise).

I have also tried to apply for free couciling in my area but there all backed up with people already so my only option would be to pay for couciling which costs more money which as of currently I don't have.
