Anybody else lonely?

I literally have 0 friends & acquaintances ever since I flunked out of school. Actually I was still very lonely even when I was in school. I keep imagining what life is going to be like as long as I continue to sit at home and build no emotional connections with other people. It feels like my heart is going to sink through my chest. I can physically feel how alone I am and it sucks.😣 Anybody else have a hard time making friends and building relationships? Anyone else interested in being friends?
