Local council refuse to help me due to no diagnosis!

So long story short, I've been having chronic abdominal pain since November 2018 following a hospital admission for fluid in my Fallopian tube (all cleared up now so not the answer!) Since the new year my symptoms have been getting worse and my flare ups are making it harder to live normally still. My boyfriend is currently my carer but he's looking for full time work in his graduate industry and may not be able to act as my primary carer if he gets a 9-5 job in London. 

I've contacted my council's adult social care team twice since January this year in order to seek help for my situation as I'm really beginning to struggle with it all. When I'm in a flare up (which at the moment can be most of the time!) I can't move much without assistance, often need help getting around my flat, can't wash my hair/body alone, can't get to my weekend job and can't make meals for myself as it means standing for too long. If the pain gets really bad I often have falls too and if my boyfriend isn't in, I'm stuck on the floor until he's home. 

I've explained all this and more in both assessments but neither were very helpful. The first assessment in January/February came to the conclusion that I should fill an assessment for another local service for help with my mental health (which was not actually helpful either) and the most recent assessment earlier this month gave the outcome that they won't be able to offer me any help at all until I receive a diagnosis.

I've been waiting for months to be seen by different departments and going back and forth with tests, etc but have no answers yet and may not for a long time! So how can I go about getting any help if I don't have the answers to begin with?!

Any advice is welcome, please!
