Too anxious to end it.

Helloo, this is my first thread so sorry if I don't make much sense.

Here goes. I've been with this man for over three years, during the whole of these three years I have suffered severe anxiety and depression issues where he has been unbelievably supportive and I could not be more grateful. We did have our own house, lovely things and both has very good jobs until I has yet another break down, I lost my job, we lost our house, and he then changed jobs into a hygiene job(this killed me as I cannot go near him in fear he beings back diseases.)

Since my last break down our relationship became very bitter. We both moved into my mums house and to be frank I can't stand him near me. He knows of my phobias of germs and illness but is not as careful as even his job requires when working, let alone for his own safety. He brings home waste, both chemical and bio waste, to dispose of the next day instead of disposing of it on his way home etc which drives my anxiety through the roof.

Aside from this we argue, daily. Sometimes Iver the smallest things like not putting the toilet seat down or something pathetic. He no longer supports me either, and often swears at me when I ask for him to help me when having a panic attack or shouts at me for being silly when I'm scared to go near him after he's been in a hospital.

I won't deny we have good days, and some great times still but the majority of the time it's bitter. I also get very depressed and like to be alone. What do I do??
