Tenant Rights In Texas

I'm disabled, please be paitent with my developmental delay, but what exactly will any of that accomplish?

I believe my roommate has deceived me under false pretenses, leaving my friends, and family behind, believing I had a potential to thrive, but instead, I'm isolated, he disallowed use of light, leaving me in darkness, unable to speak or cook, because he did not want me to make any kind of noise. Provoking me multiple times that it's His house, and that if I don't like it, I can leave. But leaving was never an option, I have no family, or friends here, I'm isolated, he eventually refused me access to the shower for making too much noise, started accusing me of causing bug infestations, messes, and anything else he could potentially blame me for. This continued false accusations eventually lead to me living in a shed in the back yard, with no water, wifi, or way to preserve food. For months I struggled... Desperately trying to make the best of a bad situation, but despite not going into his camper at all for months, he continuesly accused me of things that I had no way of causing, he does not clean up after himself, and blames me for making a mess he actually made, expecting me to have no access to basic amenities. I pay half the rent every month, living in a shed now for 5 months. Things escalated quickly when he accused me of not being disabled, just lazy and using my disabilities as a excuse for not cleaning up after him, and I finally told him to clean up after himself... And now he's telling me I need to leave. I'm not on the lease, was told I was when I first moved in... My roommate is not my landlord, so I asked my landlord if I could just pay her my half of the rent, as to not become homeless, and she told me she doesn't care who pays, as long as she gets her money, so I followed up with the question if my roommate has the power to kick me out, and she told me that's up to me and my roommate. My roommate has long since blocked me, has been ignoring any attempt to talk or reason with him, and the due date for rent is coming up. I'm scared, I've had multiple anxiety attacks, and the stress has caused me to deficate myself in public from the stress and anxiety of all this uncertainty. I don't know anyone who can take me in, I have no family, I have no friends, and all I know is, if he continues to ignore me, I probably won't be able to be certain rather I'm getting kicked out or not, and I don't know if I can pay rent, unknown to where, and who to pay it to, leading to being kicked out for not paying... And if I try to pay rent, I'm worried I'll be kicked out for pushing the subject without resolving rather or not i can stay or not...

Pinehurst, Texas.

Does that cost money?

What type of assistance am I expected to experience? This is all very new to me...

Will contacting them effect my disability income in any way? Or payee status?
