Anxiety and Depression

I feel like I'm losing my grip on reality. I'm not sure how to explain it, but it's as if everything is a dream that I can't wake up from. I quit my job of 4 years about a month ago because of the induced anxiety it was giving me. I have anxiety disorder and severe depression according to my psychiatrist. I saw a counselor but I stopped seeing them because I didn't feel like a real person with real problems to them. I just felt like a project and it made me even more unhappy. I'm taking synthroid for hypothyroidism and I found out that I have it because I kept having skipped heart beats. Every time I'm feeling most anxious my heart skips. Then it leads to depression and my medicines never work for long. I don't know what else to do.
