Totally anxious. I hope this isn't too lengthy...............or triggering?

My long-time roommate is moving out anywhere between now and March. She is looking for a house with her boyfriend (the move is on good terms) but I have no clue how I am going to afford rent on my own. I am a single mom with two kids, joint custody, which is good. However, I suffered a recent TBI and cannot handle working 2 jobs to pick up the financial slack. I am also paying medical bills, and trying to afford therapy, which is looking like I am not going to be able to pay for that either now.
I'm really scared because I don't really have anywhere to go...worse case my parents offered my family their living room to be converted into a bedroom...but afraid ex might use that as ammo against me.
So I am very anxious about this, and my future. I have such desire and dedication, and am a hard worker, but this physical setback is really hard to deal with...I could be so much more and I try to overcome it, but with a brain injury, it is just not there yet.

I guess I should be happy I have a job and kids and life. I am, but very very anxious.

Thank you for this thread, shattered sanity. It's a a good one.
