I feel like the world is ending

I'm really struggling at the moment. Going through another lot of autistic burnout. It's negatively impacting my mood and leading me to suicidal thoughts and depression.

My home situation isn't being addressed by the people responsible for it despite asking multiple times. I've been ignored, every, single, fucking, time. The NHS won't provide funding for better equipment and comfort for my situation, one involving gastrointestinal issues. And my sensory issues are treated like a joke. Almost as though they think I'm faking it. I almost had ear drums popped earlier from car tyres that make that really consistent bumping sound. On top of that the current political situations really bother me where it feels like anyone I know that doesn't support the right party is going to kill me. So I should just kill myself then? is that it? 

I feel like a worthless human being with nothing good to show for myself. Waste of space and talentless. I can't find comfort anyway. It's hard to stay happy. My life is just being ruined. I wouldn't need to ask for help if my local council could help me find/build a small house for me to live in on my own, and Universal Credit/Disability needs to pay me more to address the problems the NHS won't so I can better meet my needs. I feel a lot of despair and grief.
