Chronic Stress. Reduce chronic stress?

I'm an I.T. college student and I think i am suffering from chronic stress. 2nd yr level, because of my lack of sleep. I experience memory loss and depression. 3rd yr level, my memory loss got worst, too much depression, i think crazy thoughts like suicide,very emotional, irregular menstruation, muscle pain(neck, shoulders and back). April 6, 2017, I enrolled for summer class and before my summer class ended we had to propose our startup project which happened yesterday (May 26, 2017). I have no proper sleep this past few days because i have to prepare for proposal (i am working alone since my members are too lazy to do their jobs). May 26,2017, Proposal Day i got mental block and so i had to impromptu everything which i failed to do. I was so great at impromptu back then but not anymore. I am very concerned of my health and if this is really chronic stress, i want you to know doc that i don't want to stop studying and rest maybe you could recommend any pill to reduce chronic stress?
