Loneliness Support Group
Loneliness is an emotional state in which a person experiences a powerful feeling of emptiness and isolation. Loneliness is more than the feeling of wanting company or wanting to do something with another person. Loneliness is a feeling of being cut off, disconnected and alienated from other people. The lonely person may find it difficult or even impossible to have any...

not liking your job is 1 thing but not wanting to do anything is another.
whats making you not wanting to do anything?
Just some thoughts........
I exercise in the evening. Maybe you could focus some time on rehabbing that knee?
I'm also doing a lot of reading about spirituality. My theory is that if I can come away with one new life approach then the book is worth reading. There is something to be gained/learned from those dark nights if you look for them. I just finished " Dark Nights of The Soul " by Thomas Moore. I highly recommend it. I am hungry for life changing ideas. I find that when I get into a book that has new approaches that I can incorporate into my life, time flies by. No time to be lonely.
My few friends go to school and work and I'm a stay at home mom. Wouldn't trade it for the world but it gets lonely at times.
I try to stay busy with crafts when my kids let me stay home for an hour or so. Or I read a book while sitting in my car waiting on the kids
It's good that your knee is healing and you are able to get out. I have the opposite problem - the days aren't long enough for me :)
Walking is so great, but I hear you on not wanting to walk outside when it's dark. Maybe you could try mall walking? Or even just walking around your house, maybe with some music playing? Every little bit helps. Just a thought.
