You're right. Your current unhappiness sticks out like a sore thumb. And although people do feel sorry for you, they don't want to hang around with you because you bring them down. Nothing personal, that's just the way it is. And all of us here have felt what you're feeling, and lots of us still are. It takes time...but it also takes hard work and desire...desire to be as happy and content as you can be, regardless of your situation. Are you attracted to people who are weak and miserable? Neither is anyone else! Are you attracted to people who are strong and confident and happy? So are others! You can't rush it because it does take time...but you can start to work on it. You can start to work on being as happy and content as you can be.
"Always go straight forward, and if you meet the devil, cut him in two and go between the pieces." - William Sturgis, clipper ship captain, 1830's.
