Never to be happy

I have officially come to the conclusion that I am never meant to be happy and the way things are going I am probably going to end up alone. Please don’t try to tell me it the way that I choose the people in my life or the way I do things. At this point I have no personal life or anything to look forward to when I am not working. I heavily depend on sleeping medication to keep me from thinking about how empty my life is. I am so sad but I cannot talk to anyone because everyone expects me to be happy and they don’t understand what I am going through even if I tried to talk to them. I am on a rollercoaster that cannot seem to stop and I am losing my mind.
