Information needed

Hi everyone, I'm new to here so please help if you can. I'm a type 1 diabetic pump control, I also have Rheumatoid arthritis and registered severely sighted. I have a husband who is self employed and works when he can around me. I try to work 25 hours per week I get pip. I have a mortgage with 7 years left to pay on a 1 bedroom flat 1st floor which im struggling to get up and down due to sight and pain. Ok so that my back ground. So I was told last week that my boss of 10 years has sold up and the new bosses/owners arrived the day. so my old contract will end in 4 weeks which I could take redundancy from them which amounts to £1900. The new owners our obliged to take us on under new contract with a 6 month probationary period which he has said he won't want some of us and my old boss only kept me on due to feeling sorry for me. I know my health and sight our a big work hazard but my question is what do I do. I feel like I won't get another job therefore I'm going to have to sell my flat as I won't be able to afford it with just my husband wages but what do I do. The cab told me we can't get help cause we r mortgaged and my husband is self employed. Someone please help where to start or what direction I can take. Sorry for being so negative I'm just so sad and unsettled. Thanking you in advance.. x
