Frankly the best thing to do about depression is to seek help. It doesn't have to be a professional. I cannot offer my assistance with that.

Loneliness I could offer a suggestion that may or may not help. Sometimes loneliness stems from unsatification (that's not a word, btw) with where you are at. Try to do something new. It doesn't have to be something scary. Think of something you like to do: watch tv, read, play games, cook. Then, find a group of people you can do that with. Join a scrabble club, take cooking classes, go see screening of old movies. Interact with new people with the same interests as you.
