Just feeling so alone...

It's been a while, but... This deep well of loneliness has been keeping me up at night and I wanted to write down now. I have been drowning in work (mostly because I bring it on myself and I can't say 'No' to people in need), but the alternative is going back home, to a home that doesn't feel like a home anymore, it is just four walls and then nothing. It offers no warmth to me, no comfort. I stare at the ceiling these past few nights just wanting to sleep, but my mind and heart races to the past filled with painful memories. I have never been much of a drinker (like once a year) and I've never done drugs, but maybe I suppose I can see why people choose that, it helps them forget. Forget all the pain and loss... I am unsure what to do, don't really know why I came on here... just hoping for some solid advice. I know my shyness and introverted-ness doesn't work in my favor when it comes to socializing or attending parties and what not, but this loneliness eats away at me and now is affecting my sleep. Any advice will do... Sorry about not being overly specific, but I thought I could put this thought out there... Thank you for reading this and I hope some good comments come my way. Sorry if I bothered yall, especially around the holidays, didn't mean to bring down the room when every one celebrating and enjoying the season.
