I'm the same. Literally all I've done for eighteen months after my condition deterioated is get food/medication/go to essential appointments if I could get there and that was dependent on being able to get out in the first place. That's it. Don't see anyone or do anything else, no exercise.
I still need to do those things as before (meds/food daily as I've no space to store food and can't get more than a day of medication and no I'm not going into why that is) despite being at risk and sent a letter as I've no one to help, the volunteers here are not being properly checked and I know my abuser has been allowed to volunteer and I don't want him to know where I live now and he'd have access to that from the database.
My appointments have now stopped so I've no medical/mental health care at all as my device rejects Unknown calls (put in place for my safety) and it's not as simple as buying another even if I could afford it as details are necessary to set it up and will mean block in place on them as well.
I have lost my temper, and I'm not proud of that, with people whining how boring it is to 'just exist' - many many people's lives are lived like this every single day, and it's not an excuse to let rip at people - when my condition worsened no one gave a damn at the huge changes in my life, or impact on my mental health.
I've no functioning to join any social groups, go to library, or church etc. I'm needing to ration the things on social media I muss doing because when this is over it'll be a struggle to adapt without those things again.
No medical care at all indefinitely though is terrifying given my medical/mental situation but I can't do anything about it.
