Maybe try to stop concentrating on people and give your love and care to animals instead.
They are fun, are great friends and we can learn heaps from them.
And, eventually, when you will feel better about life and yourself, you will find people come to you naturally
OR
you will find YOU are the one who matters
and that the real Friend is Within.
Much luck.
You know, I hear you and feel you.
We all struggle...
But even this will pass.
