Maybe this is a unique idea of mine, but I would like to share my feelings here as a person who has or is dealing with depression. I agree that making friends and reaching out to them etc. to cope with your loneliness is a problem that is frequently spoken about. But for me, it's got to be a true friend you know you can trust. What I find effective in making me feel better for myself is simply distancing myself from poor friends or blocking myself. There are mates that you know are not right for you and ultimately dragging you down. Talking to them would not make you feel better or help you develop as a person. Why waste your time, then? It's finding the balance between finding and not isolating yourself for the right people to talk to.
