sorry to hear your going through a rough time, but like the other's suggested with you working, can you not move out of your own, or back with family. i would think living with this same person would make it emotionally harder for you to move on.

as for the things you used to like to do, try taking baby steps. start with painting.... maybe a do alittle bit of that and see if that makes you feel calmer or less emtional about things.

there is always a light at the end of the tunnel. things may look bleak right now, but as the expression goes..THIS TOO SHALL PASS.

take care
