Where did you get diagnosed with BPD? That typically stems from abuse/neglect in childhood.

I dont see whether you are male or female and how old you are. If you are a male around age 18, this could be due to hormones and not having a chance to burn off energy. The teen years for alot of males can be very hormonal and they can get urges to
wrestle and burn energy. Thats why a lot of males like sports, and even "contact" sports so they can burn that energy off.

I don't know you well, so I am just guessing here of "could be" reasons so I am "not" critiquing you ok?
