what do you do on days where you don't feel like doing anything

i get days, a lot of days, where i just want to laze in bed until the afternoon, stay indoors, not do anything....not wash or brush my teeth, heck, not even make meals for myself....not answer the phone, not open mail, just sit in my chair and be at the computer, all day....i do struggle with mental health probs...i have a mental health worker i see every month....my mother is my main support system, but my mum lives far now......i have lived alone now 20 years in a little apartment and i'm just here alone all the time.

i haven't been swimming at the gym for over 5 months, i lost the drive to do it and get there....i feel trapped in this dark gloom.
