Help To Prevent Me Becoming Homeless Due To Tenancy Ending

I currently suffer severe anxiety and depression due to finding a friend passed away from suicide. It really affected me and I find it hard to be ok like I used to be, I am currently in shared accommodation after moving back to my hometown and have been given notice to leave due to my short hold tenancy ending I literally have a few weeks to leave I have no where else to go and don't know where to turn. My anxiety is through the roof at the moment due to the stress and I cant think clearly at all. There are a few properties that are vacant in the town however due to my illness I am off work and rely on ESA to survive at the moment so I am unable to afford, rent upfront deposits or any fees. I really don't want to be homeless with anxiety as I dont think I would cope at all. Any help will be appreciated and I will update my page to let you know how I get on..

Thanks
