I (29f) was working two jobs when the first lockdown happened, now I only have one job and furlough is being calculated off my old wages! What can I do?

Cautionary warning- suicide attempt mentionI have never posted before, so forgive me if I say something dumb.I (29f) work as bar staff in a pub, and have been told by head office that I will be receiving my previous furlough money (£75 a week) despite working way more hours since lockdown ended in July.I no longer have one of my two jobs which I received £65 furlough a week from because it closed and my rent is £100 a week plus phone bill and food etc.Feeling very despondent that I have been working a LOT but the government has advised them to use my pre lockdown wages when I'd only been working one or two days a week because I was working a similar amount at a second job- rather than my post lockdown wages where it was my only job and I was working 4/5 days a week.My second job (also a pub) has since closed due to the building being taken by the council to be refurbished (listed building, they want to turn it into a theatre, works won't be completed for several years).Some coworkers are in similar predicaments.Not sure if whether universal credit is something I can even claim as I am not on a tenancy agreement (me and boyfriend and his dad live together, boyfriend's dad is on tenancy but we all pay rent, landlord knows I live here and is happy with the arrangement).I've been informed that my holiday hours will be used to "top up" my wages but I used up a large chunk when I took a week off in September following a stress induced suicide attempt in August (I have bipolar disorder).I do not come from a family with money. My parents live on a council estate and have no room to take me in (my kid brother now has my old bedroom and it's a flat so it's very cramped, both parents are hoarders with untreated mental health issues so my relationship with them is a bit strained in some ways)My boyfriend worked at the same (now closed) pub as me and he is in the same boat as me but worse cause he didn't have a second job. There was a chance that all the staff of that pub were gonna be hired on by another pub that was thinking of reopening but about a week ago we found out the two respective owners couldn't agree on terms and decided to not pursue it. Because we were waiting on this news and had previously been reassured by the higher ups that all was going well boyfriend didn't seek out a new job directly but had been putting feelers out for other hospitality work.Boyfriend's dad is self employed as a painter and decorator and was on universal credit during lockdown and is awaiting the next self employment grants.I have had to clear my savings out multiple times to buy food and cover bills during the last few months so there's only about £50 left.I was wondering if anyone can give me any advice regarding what I could do? I'm already job hunting, selling some of my clothes and other possessions, and we live off of the cheapest food we can.Sorry if this was long winded I've just finished a very busy shift at work (everyone getting their last pub nights in) and been crying since I got home, calmed down enough to type this out. via /r/UKPersonalFinance https://ift.tt/32scc3R
