Loss of mobility in face and left arm.

I have major depressive disorder and severe anxiety for which I take flunil and nexito 15 mg. I also take zolfresh because I have sleep related issues and Toficalm and Migabet for anxiety and panic attack. I also take modalert 200 for attention I have back to back exam and submissions which means very few hours of sleep. And I have developed chest pain issues whenever I am stressed. Recently I have been feeling heaviness in my left arm when I'm stressed and a few days back I lost mobility in my left arm and left side of face. It starts as tingling and then my tongue gets heavy and doesn't roll. Some say it might be due to sleeplessness, some think it may be due to BP issues. What could be the cause and what would be the solution?
