Mentally/emotionally drained

At the beginning of the year I was let go from my job because I notified them I was expecting. Then I miscarried. A couple of weeks after finding out that we are expecting after miscarriage in Feb, I found out that I have thyroid cancer that has also spread to other parts of my neck, nerves, muscle. I have surgery this Thursday. I went to the ED Friday night for a migraine that wouldn't go away. After several attempts at helping, the doctors were at a loss and they admitted me. I also suffer with hyperemesis. They found my potassium level was low and causing so issues with my heart. I was discharged today. But with all of this, my anxiety and depression is at an all time high. I don't eat, all I do is sleep, constant headaches, and I feel at battle with my brain daily. I do take meds and go to counseling but wondering if any other mommas can relate in one way or another?
