Help me plz...

Well, I'm a 34-year-old man, to begin with. Over the past few days, my depression has been worsening, along with my anxiety and PTSD. I constantly feel on edge, and being in physical pain all the time doesn't improve my mood either. I just want to feel normal, whatever that means these days. It really sucks; every day feels the same, and nothing seems to get better. I'm sorry I'm not great at expressing how I feel. Maybe I deserve all of this; I don't know.
