I had a particularly hard time getting myself to leave the house. Congratulations on getting to your doctor’s appointments.
I started super small. Every day, I would walk to the end of the driveway and get the mail and the papers. Most days, it was excruciating. It eventually got easier.
Next, I planned somewhere to go. I planned only that event for the whole day and rewarded myself when I did go. That got easier after awhile as well.
There are still days when it’s just not happening and that’s ok. Maybe you could start really small and take baby steps. I understand about your hair. I didn’t have mine cut for over three years because I just couldn’t get there. I finally got there about 3 weeks ago. It was well worth it.
Good luck and best wishes on gradually getting out of the house. I believe you’ll get there.
