Sorry to hear you're struggling at the moment, I'm also repeating 'alone' in my head the last few days, I wish it would shut up already! I've started to force myself into doing things and I'm quite enjoying them but at the same time it feels like my heart is screaming and leading me to make bad choices.
There are other symptoms to Depression other than over sleeping, like loss of interest in things and suicidal thoughts etc. Hope you feel better soon :)

People with depression can also suffer from a lack of sleep as well as sleeping too much. Do you have a Therapist you can talk to about this? A close friend who would understand? Have you thought about volunteering somewhere that would give you fulfillment, new friendships, and give you less time to feel lonely? Hugs GB

I don't sleep a lot and I'm very depressed, it really can effect people differently. Some sleep more, some sleep less, it depends on the person I suppose. There's a few different symptoms of depression as well, people can become no longer interested in certain things (it has happened to me a few times) or they can have a loss of appetite, or suicidal thoughts (both also have happened to me) as well as other things. Anyways though you might want to try speaking to a doctor perhaps.

the thing that depression sleep is called is escape sleeping...trying to escape from depression....

anyway people have said a lot of good stuff here...if need be check out the gym for some exercising...I hate exercising but if I am depressed it beats the heck out of getting suicidal....:-)

Anyway have you thought about meetup.com?

I don't get depressed when I'm lonely--just angry that I am lonely!!!!
Anyway, I do things that give me pleasure like watching a movie or talk to a friend who doesn't have anything better to do. One of my good friends and I are planning a short road trip again. The last time it was really fun!
