If your landlord wants to evict you they must have give you proper notice using the correct 'RHW' form. If they haven't then talk of evicting you is just that and you can ignore it. If they have and the notice is valid then whatever they did or did not tell the police, they want you out. You don't have to leave when the notice period expires. The landlord will need to ask a court for an Order of Possession. You can challenge the claim for possession. If the court issues the order this is effectively telling you to leave on the specified date. If you still don't leave the landlord must ask the court for a Warrant of Possession. If that is issued, the landlord can use High Court Enforcement Officers (Bailiffs) to make you leave. As I explained if the landlord succesfully takes any court action to make you leave, you may be told by the court that you must pay the landlord's costs. You can check whether the notice you have received is valid and how to challenge it here:

Re. registering with the council for a council house; with respect if you have a device that lets you post on Tattle I think you can probably register with the council. The message that you need to 'update' probably refers to the device's operating system (which is free to update) not the actual device itself. If you can't register this way I understand that every public library in Ceredigion offers access to a computer.
However if Ceredigion council is anything like the councils that I deal with in England, even if you are accepted onto the waiting list, it could be some time before you are offered a council property so that probably isn't an immediate solution. Edit: just read an article from last July that says that the average wait for a one bedroom property in Ceredigion is 783 days!
The Ceredigion Council website homelessness webpage appears to offer a wide range of services and support. I expect you have already engaged with them but you haven't and if you are in imminent danger of being homeless, you should contact them now.

I also found this local charity that helps people threatened with homelessness:

I don't know anything about hoarding disorder but as far as I can tell, treatment is either arranged through your GP or privately. The MIND website lists a number of organisations that offer support (including completing application forms):
