I've been on Lexapro for 6-7 months, 20 mg, can it cause tardive dyskinesia? How do I wean off of Lexapro?

My pdoc told me that Lexapro could have not been the cause and that the 2.5 mg of Abilify I took was the reason for it. I only took Abilify for two weeks and I stopped, then experienced spasms all over my body. A week later, I still have muscle spasms and it is increasing.

Can I try not taking Lexapro for a day to see if it will go away? If it is the Lexapro. Can this be permanent? Can 6-7 months do enough damage?
