How to Get Past Burn Out When Living With Chronic Illness

Hi I’m just really feeling burnt out right now. My health has been really bad these past few weeks and I’ve been in severe pain yet I just keep pushing myself harder and harder. I had seen a pain specialist and he told me I just had to keep living life like every else because my pain was all in my head and wasn’t even that bad (he’s an absolutely jerk wad I have another post on here about him) and because of him saying that I just keep pushing myself when I have nothing left in me to keep going. I feel like I’ve reached my breaking point now I’m in pain I’m depressed and now I’m so exhausted I have no energy left. How do I get past the burn out? I still have to go to work and everything it’s like I’m not gonna get a break but I just can’t do this any longer. Im so tired and miserable and in pain I just can’t keep pushing forward. How am I supposed to rest and take a break when there’s no time to take a break or rest? I just want to feel better! No one told me how hard it was going to be to live with chronic illness and I feel gypped out of having a normal life
