What you describe sounds exactly like me. After work I am very exhausted and I need to rest.
At work I need to talk a lot on the phone and that hurts my head, makes me dizzy. So after work I am not in the mood to talk much.

I sometimes don't answer phone calls because of that.

Also I cannot say today how I will feel the next weekend so I cannot make plans.

So I stay home, feeling lonely a lot of times. When I do have to go somewhere I put in my earplugs.
