Abolish universal credit

Im a single parent, and i suffer from anxiety and have done for years, ive worked for years trying to earn, since ive been on universal credit i have been in rent arrears and other arrears, i have never been in arrears before so this is very stressfull, which has made my anxiety 10 times worse, im currently signed off of work with stress and anxiety, as i feel like i have no hope! I got told the hours i work dosnt matter anymore as the universal credit wavers and makes up for what you havent earnt, which is all good if they hadnt had left me 8 weeks with no money! They then say halfway through my 8 weeks that i can get advanced payments! Those advanced payments went to people i owe money to and still trying to pay arrears! Im not getting anywhere! Im in a 3 bed house with one son who is 9, and 8m paying bedroom tax, for the spare room! Im trying to downsize but im not getting offerd anything because im in arrears i presume! Im still not getting anywhere my mental health is up and down constantly and feel i cant cope.
