I’m deeply unhappy

I feel so lost. I have no real friends, I am not heading anywhere goals or career wise and I’m struggling with the same issues I did years ago, not having overcome even one. I’m developing more and more bad habits and I can’t seem to dig myself out of the hole I’m in. I look at other people’s lives from the outside and wish I could be there as well. I’m more sad than jealous though. Recently a dream shattered and I’m left aimlessly waiting for something to come replace it and give me a chance to feel hope again. Why do I make it so hard when it could have been so easy?
