You are clearly not better and your GPs abuse of duty of care sounds awful.
I cannot critique anyone for doubting as we are all entitled to our own feelings.
You have the right to help and you are being failed, if what you say is true.
I did a quick Google of Llanelli and please see screen shots attach. Not preaching and you said you had mentioned MIND though I say contact again, I believed they were open to help all and non judgemental so please try again.
One of the services say for domestic abuse support, though if that is not a cause /effect of your condition, why not reach out and tell them about the reality of your situation. It will not improve unless you get support.
Can you not set up a new email? I have more than one across outlook and Gmail.
Re utilities, if your situation progressed, there is a multi service provider, UK based who are good. Utility warehouse. They offer, unsure if you need electric and or gas (they do if electric only) unlimited SIM £18 month. They can do quote on line.
I do not know what else to do, though empathise as since July 2020 my life turned upside down though making tracks to recovery. It is going to be a long hard winter and it is harder for those of us who are vulnerable.
It is hard to believe how badly you are being treated by those responsible for our welfare, though hope you find the strength to reach out as you need support, and hopefully the next person will listen.
We all have the right to ask for help. Being isolated can make the voices in our head tell us that we are not worth it but you need to push for you.
Sending best wishes. I really do not know what else to suggest.
Hope it is ok to post the following info Mods, just concerned for our fellow tattler.
I wish you the best.
