Breathe deeply. Breathe deeply again.
Its great that you might have a roomate; I have 2 roomates, they are very nice women, they are also artists..today they managed to get me out of a funk, we laughed and talked. It makes a difference to have friends to interact with...
See at all these things as added evidence to how great your decision of leaving is, for you...
Today dealing with some toxic people I decided to be glad they are not part of my family nor friends and soon I won't have to interact with them at all.
Hugs.
