I'm like you, but I have come to know that human relations are very important to mental health and mind altering substances only alienate us more, especially if it is in your nature to be an "alien".
I make a commitment to loving others and cherishing my friends. But, it did take time and commitment. I had/have to trust that I am worth it and have something to offer. I'm still working on it and drinking stands in the way.
What it comes down to for ME, is that it is not all about ME. Truth be told, I feel much more authentic when I reach out and care for others.
That said, I do appreciate you expressing very real feelings for us "loners/misanthropes".
