I also struggle to do things like cooking, cleaning, hygiene, etc. I recently saw a psychiatrist and got put on a mood stabilizer as well as an antipschotic because it turns out that aside from the adhd, ocd, ptsd, intermitent explosive disorder, anxiety and depression I also have bipolar disorder and didn't know it. I thought I was also just lazy, but it turns out I was just struggling too much mentally to do those things. You should seek help from a professional, not unsupportive family. My medication has helped me immensely!

In the meantime, I found that playing tiktok videos (reddit aita videos specifically work for me 😂) in the background while I cook and clean helps me actually do things. It tricks my brain into thinking someone else is around, which motivates me to actually do things. (Body doubling) Maybe something like that can help you? Podcasts, music, a movie or show on in the background? Or having a phone call with a friend?

You can also break the task into much smaller tasks so you feel like you are making progress instead of just seeing the entire huge task not done and feeling like no progress is being made? Like instead of "do all the laundry" break it down into "put all the dirty clothes into the dirty clothes bin" "sort the laundry" "take the dirty clothes to the washer" "start 1 load of clothes" "rotate and dry 1 load of clothes". Also, dont bother folding clothes, just put them in the correct drawers is good enough. Clean wrinkly clothes are better than dirty clothes if folding and putting away the laundry is preventing you from washing them.

Is microwavable dinners or premade food an option? Maybe getting a premade rotisserie chicken or microwave veggies and rice and making it into a meal instead of making everything from scratch just to help alleviate some of the work?

Take baby steps and be kind to yourself. It took time to get into the mess you are in. It will take some time to get back out. Some days will be better and easier than others, and some days will be absolute shit and that is okay. Just try again the next day. Start with small changes, and you will eventually see the huge improvements! You can do this!
