Feeling Tired and Empty: A Cry for Help

I am just so tired... of everything. Lately, I haven't been myself as in being more depressed and unmotivated... Nothing seems to get better in my life, and often times I just shun away, and avoid people. I don't want to talk to anyone but I know it is not good to do that because of past experiences. I know it never makes me feel better when I avoid people. I'm just so tired of the expectations people have for me. I'm so tired of being in the wrong all the time because I was standing up for a friend. I'm tired of my job, I've been so tired of it for a very long time but there is nothing out there that pays as well.... I'm just tired of feeling this empty void inside me, and that I don't want to be here physically. I do not know what to do because I feel alone, tired, anxious, and depressed. I feel as though, my meds are no longer working for me, and I'm tired of trying to take new antidepressants because it gets so tiring... I just wish I could find a reason to be happy since I have some good things in my life but it doesn't give me any joy at all. I feel like I'm here yet so far away... I do not know what to do anymore
