How to manage side effects from 30 years use of Lorazepam

I have been given this drug for over 30 years. My dr does nothing to help me get off of it so after I did my own research I thought I could tapper myself off. I’m 5 months in and side effects have only gotten worse. I’m hoping someone on here has had these same issues but found a way through. I need guidance. I don’t trust anyone who hasn’t dealt with this personally. Each day I suffer from panic attacks and depression. Taking anti depressants gives me horrific night terrors which only fuels my anxiety. Recently I wake up to panic attacks in the middle of the night. My depression grows every day which is affecting my work and personal life.
