Hello costello,
Some of what you describe reminds me a bit of my own child. They could also leave a trail behind them and weren't always good about respecting other people's boundaries. There were times I attributed this to the abundance of energy that comes with mania and other times I thought it might be related to those fragmented ego barriers wherein, it can be difficult to determine where you end and the rest of the world begins.

I also found, because our child was in their young adulthood as well, that there could be periods of what was probably healthy resentment that I experienced as challenging, sometimes unhealthy behavior. It's difficult to strike a balance. This is one area where peers and other people can be helpful. They can say something and you can say something and it might be the exact same thing, but your child may be more open to hearing it when it isn't coming from someone who is a parent.

Living with someone who is in an early stage of recovery can be very challenging for all parties. You noted that you can't take him out of the house, but can you bring others in? In the link I shared from Windhorse Communities, they talk about creating a care team. This is beneficial to the caregiver because it helps to prevent burn-out but it's also beneficial to the individual in recovery because it helps maintain and restore social relationships and provide structure. It's possible you might be able to create your own care team drawing on local resources.

Admittedly, in the early stages of my own recovery I preferred to be left to my own devices. I was not keen to socialize widely and often found it quite draining when I did. I mostly kept to myself for the first few years and I think this was healthy for me. Maybe you could talk this over with your son and see how he feels about interacting with others right now.

Other things you could consider are:

- Declutter his personal spaces. It will make tidying efforts easier for him to tend to.

- If he makes a mess in the kitchen, perhaps spend some time on the weekends preparing meals that can be eaten, reheated through the week.

- Baskets for holding personal care items in the bathroom and some disposable cleaning cloths might help streamline tidying efforts.
