Can't Sleep

I sometimes am scard to go to sleep. Because when I wake up I hope I am not in pain or have the burning in my arms & chest. When I get up I have to take a heart burn pill along with a anxiety and depression pill just to get throw my day . If I don't take the pills I am in pain and my arms & chest are burning all day . I just don't get how I was fine 3 weeks ago & now I am going throw pretty much feels like he'll . I used to go to the gym everyday workout eat right now all I want to do is stay home in bed . Because I fear something going to happen because of the heartburn and anxiety .I just don't know what to do .I just want to get better & go back to being me.
