I also went through such a multitude situation. Many problems at once. I went to a renowned Psychiatrist recently and eventually I was back in studies after some time.
A good session and medicine really help gain your concentration. Stress is a medical condition as a result of chemical reactions, tabs suppress them, also helps regaining much needed concentration.
You'll feel the dr has become your friend. Who understands your situation and lends you a hand to way out.
Remember, the domain of Psychiatry is included in main OPD. Which means anybody can get stress due to life and is normal nowadays. There's nothing bad rather helpful to see a dr, who comes to know you deeply and knows the condition better than you.
Warm prayers
