You should not play soccer anymore unless you can be disciplined to not head the ball. Heading the soccer ball has been know to cause brain injury since research done in the 1970's. And, stay out of the goalie box during corner kicks. The risks during a corner kick are high.
I had to give up soccer so I started training as a distance runner and did quite well. The endurance conditioning from soccer practice enabled me to quickly become a champion distance runner.
Besides, girls soccer during the late teen years can get quite violent. My niece was on the Olympic development squad and quit to avoid the injuries caused by the violent play.
You have plenty to look forward to without putting your brain at risk again.
My best to you.
