What can I do to relieve stress from tiger mom?

Tiger Mom?? I assume you have a type a, goal driven, perfectionistic, controlling mom. Please try to talk to her about how you feel. That may not work. Next, try to explain your stress to your father if that does not help. A school counselor or school nurse could help a psychologist or a family doctor could try to intervene. A trusted adult could possibly discuss the situation. If you are an adult try a timeout.
