Get up early, shower, shave, get dressed and GET OUT THE DOOR. Sitting in your own prison will not change anything and it only erodes your mental state.

Until you find work; volunteer, walk the neighbours dog, anything.

Until you can go back to the pool; walk, everywhere.

Until you have place of your own: stay away from your mother from as much as you can. Go to the library, go to the mall, go for another walk. Stay in touch with your friends, no matter how depressing. Many jobs go unadvertised. The more people know that you are looking for work the better.

Attend an Al-Anon meeting. Your mom may not be an alcoholic, but read the 12 steps and substitute "mom" for "alcohol" and you will see what i mean.

Priorities:

Fight isolation at every opportunity.

Walking (she can't whine about the car if you don't use it)

Wake up with a purpose (even if that purpose is to get the hell out of there for a few hours)

Above all , you must realize that you are stuck in a prison where the doors unlock from the inside.
