Sudden jerks, Anxiety. I need help.

Hello, I have been facing sudden jerks throughout the day since last 8 months. I also have anxiety and get frustrated frequently. My vitamin B12 and D levels are low and have high BP. I am facing all symptoms for B12*deficiency and GAD. I have consulted couple of doctors out of which one suggested to take B12 and D supplements because it could be a reason the way I am feeling and also also consult a psychologist to work on my issues but not take medicines for it as of now. The other one gave me a blood pressure medicine which seems quite heavy and I might have to take it for life. He suggested me to go to a psychiatrist and take medicines if I have to in order to get better. Both of them might be right and have different ways of treatment. I want to get well but eating medicines for life to keep myself sane does not seem good. Please suggest my course of action. I am happy to provide any info. I need help.
