Feeling like falling down. Dizy. Life.

For the past 1.5 months, I've been feeling like I may fall down. I have been taking patanjali megha vati extra power because I was not able to sleep. I am working in Bank. In 2017, I had the same issue. I was diagnosed with B12 deficiency and anxiety problem. I was prescribed dulane 20, vertigo medicine, anxiety medicine and Vita B12 injections. That made me fine but that resulted in sexual problems. I have been addicted of Masterbation since 17 age. Wife wanted to get a child hence I had to take sexual wellness medicines ayurveda alopathy etc. Now we have 8 months child. But my problem is when I try to make my mind fine, I become victim of sexual problems and when I try to cure sexual issue, brain and nervous system issues occurs. As of now, I want to know which medicine I should take to stop vertigo, diziness, brainache, concentration issue, anxiety. I want to consult a doctor who can treat my brain issue without harming sexual life.
