Do you feel so ALONE in this world?

I feel its me against the world, and its scary. Ive grown apart from many friends..miss that connected feeling. I have no true family to talk to, they are all wrapped in their own worlds or are narcissists. I get super anxiety to date, as I feel Im not whole for a guy... so it feels like a giant hole most days, trying to climb out, HOPING to find someone who would accept me, hoping to find anyone kind. Then you feel so hopeless, and like you are hanging on by a thread. Do you feel this sometimes?
