Am I the only one here who is completely and utterly alone? It isn’t an exaggeration. I have no family, I have no friends. I was doing OK yesterday. I even got some quilting done which is my passion, but I’ve done very little of it in the past few months. Today, I can’t get off the couch (as you may be able to tell by all of my posts!)
You're not the only one. Several people here have no living family or friends. Many have nobody to list as their emergency contact. Others are 1 person away from being in that boat. I have my husband, and a brother I love although we aren't really that close as adults.
I am in a new city where I don't know anyone (since last fall), and apparently none of my friends want to make the 1.5 hour drive to see me (I don't have a vehicle right now). We do talk on the phone.
I belong to a live depression support group, which is great. Most people in the group have family connections.
I will be your friend, if you like.

I'm in your age range (and my husband is 64)I have a few friends from forums such as this and it's great to have someone to talk to who know about mental health stuff.
