Hmmm I don't really know what to say to make you feel better, I kind of understand what you are saying especially people like to hang out with funny/happy/humor people than miserable ones, so I don't usually revealed my depressed side to people, or unload my negative energy to them.

When I was very low previously, no matter what others said to me or advice they gave me, it just didn't stay in my brain, still sitting my butt in the darkness, keep thinking the negative thoughts. Somehow I remember I read a post somewhere that said "no one can help you but yourself", it is true....so since then, I keep self talking to myself, any ways to take myself out of this darkness. And I feel better now, not good but ok, better than before...so I hope you can somehow find the courage and energy to start self talking to yourself to bring yourself out of this misery, if not fully out of it, partially out also good.
