Needing urgent help

Ever since I was a child I was expected to succeed.

When it came to that Id go through severe stress. This stress led me to procrastinate.

Every A+ i got was through severe unnecessary suffering. Im sure my body is older than I am from the constant cortisol.

Now im in university and have my last exam to finish. It is the hardest exam ive ever had to take. Its like finishing the whole year of exams in one day. I still have the same problem:panic attacks, procrastination, hart palpitations, stress but one more new issue: I cant focus now.

I go through 2-3 sentences and my mind wanders.

Ive been trying every method there is to try.

I need serious help. So all I ask is on tips on choosing the right medication to chill and focus.

Thank you for any tips!
