Is this depression or something more serious

I've been stuck in this condition for one year. Thought it was depersonalization but it's not. First I don't feel my body, my limbs and head. They feel completely numbed. My consciousness and vision are very altered. My body feels very distorted, also I feel detached from my own body. I have ringing in my ears. Around 5 pm when crisis kicks in it is hell. My body is numbing more and more. Ringing in my ears is getting louder. I don't feel my head at all. I feel like I'm in horrible trance like state or even feels I'm heavily drunk. My eyes are like they are going to explode. My internal organs are burning and squeezing me inside. I have terryfing, psyhedelic like sensations in my body and head. I feel literally like I'm dying. it's extreme mental torture, pure hell. I'm severly depressed, crying every day and highly suicidal. My life is destroyed. I'm unable to do anything. Medications doesn't help at all. Could this be depression or brain damage or mental insanity.

anyone?

How long have you have been on prescribed medications? Have they tried different classes or dosages of meds? Are you currently seeing a therapist or counselor?
Have physical or endocrine issues been ruled out through lab work/blood samples, tests, etc?
I can't diagnose this, but I would suggest continuing with your primary doctor. They may want to refer you to a specialist if they feel that your symptoms are outside their field of medicine.
Best of luck to you.

One year. I've tried different dosages. I'm seeing a therapist. She said it is ocd disorder but I don't believe. Blood tests are fine. I did MRI scan and it's fine too.
