Klonopin (Clonazepam) Withdrawal. HELP!?

I am not gunna go into detail so i'll make it simple. I was taking 1mg clonazepam everyday for about 3 months, basically the doctor has cut me off cold turkey and I am having pretty bad withdrawals. Dizzy, Nausea, Headache, Lack of sleep, No appetite, Bad Anxiety, Panic Attacks.. It's basically just hell. I don't know what to do. She gave me Lexapro but it has given me nothing but bad side effects plus the withdrawals I am already having. I'm not planning on going back to that doctor because they refused to give me Clonazepam which is ridiculous because they didn't taper me off. I am scheduled to make an appointment with a psychiatrist soon but I feel like I can't take it anymore. I seriously feel like I am losing my mind and I just feel so sick and weak.. I don't know what to do because Lexapro is not helping. My only hope is talking to the psychiatrist but even then, i'm not sure he will prescribe me the Clonazepam. These withdrawals are terrible, I don't know how long I can go..What should I do?
