I really think the best thing for you to do is move out
@J_trustno1 as long as you are living there, you are going to keep suffering in this way and getting caught up in these thoughts. Actions often speak much louder than words. It's clear your mother isn't able to hear you for whatever reason. You can't make her choices for her, and you can't force her to make the choices you want. What you can do is make your own choices. Shift the focus to what you can do instead of what you would like other people to do.
Your voice in these posts often reminds me of a child or a teenager. That is understandable as that as where a lot of the hurt and damage was done. And at those times you were powerless to make the choices you can make now. But you're an adult now. At 27 (? Sorry if I've remembered that wrong), you really don't have to continue to live at home and put up with this. You couldn't leave then. You can now.
I know you've said in the past that you can't afford to move out, but I'd like to challenge that. I appreciate that you probably can't afford to move out into your ideal place, but I don't believe you need to wait to get your perfect job before you make this move. There are cheaper options. Bedsits. Flatshares. Houseshares. No, maybe not what you want long term, but would living in a bit of a dive for a bit really be any worse than putting yourself through what you're putting yourself through everyday at the moment, living where you are? I lived in some proper shitholes and worked some really crappy jobs in my teens and early twenties. It was better than going 'home'.
Get proactive about moving. Channel the energy you're currently using getting upset about other people's actions into your own actions. Use this to get yourself fired up about getting out. Look at how much you currently pay your mum towards rent and bills and food etc and do the maths to work out what you can afford. Start putting every spare penny away for a deposit and first rent.
Taking your own independence, making your own choices, will give you much more power than it will coming from anyone else.
