Sorry you wish you hadn't started the thread, Kaylasmum. We all make mistakes and it's easy to point the finger.
Let's look at the bigger picture for the moment. Anxiety that prevents you working is not ideal. Anxiety that requires your not-tiny children to be always near you is not ideal. Quite aside from the impact on your earning potential, this is your life and you aren't living it while you are having everything dictated by these illnesses.
Illnesses are curable. There are things that can be done. I get the feeling you don't quite realise that there are options, that change is possible.
I also think that is likely to be to do with living with someone for a long period who is not great for your self esteem.
Look, in the nicest possible way, lots of people earn a living while all kinds of shit goes on in their lives. Adult children with problems and significant bereavements are reasons to ask for temporary flexibility from your boss, not reasons to give up and say you can't work, or that these issues have "taken up" a decade and a half. Seriously. you are worth more than this. I am not saying these things aren't difficult and painful. I just think you need to value yourself more, place yourself more at the centre of your own life. If you have issues, get help with them, work through them, phone in sick and lie through your teeth the morning you can't stop crying and say you had a dodgy prawn, but KEEP GOING and look after no. 1.
You have three no. 1s - you, and your 2 dcs. They are your number 1 and you have to put yourself in equal top place, because they rely on you.
YOU CAN DO THIS.
There are women on here who pulled themselves out of shit by their bootstraps in a women's refuge. There are women who started with nothing, and women who lost everything and started again.
I have heard "you can't put a price on your self respect" and I loved my house and the idea of a family so much I thought I could throw my self respect away. But over time the loss of my self respect was making me ill. I am safe here in my house with my 2 dcs and suddenly things that never seemed possible before, are. you can do that too.
Who do you have to talk to in real life? Do you have a church or anything like that that you feel any affinity for? Or, as others have suggested, phone womens aid
I haven't read your other threads, but I feel like the wife and the house are almost side issues. The issue is why aren't you reaching your potential? If you were, you wouldn't give a shit about this waste of skin you live with. But its a vicious circle, you need to get away from him to come into your strength
