Felling sad

I'm sorry this is just a rant idc if no one reads it I just feel so sad and depressed. I feel like I'm so worthless and I can't accomplish anything that I set myself for. I miss the person I used to be and I'm letting this depressed feeling take over my body. The man that I love and would do anything for doesn't care for me and makes me feel like a piece of Sh*t, and the more I think about my life the more I see how I make no difference for anyone. I used to have a lot of people that cared about me and I let them go. I locked myself in a box and i feel like there is no getting out. I don't take care of myself anymore I don't wanna be around people I have no one to talk to. I feel like I shouldn't exist. I don't know what I'm doing on earth anymore I pray every night so God can give me a light but I feel that even when he's talking to me and showing the right direction I choose not to follow that path. I'm tired of crying And tired of trying yet I can't do anything to change myself
