Replying to Shoulder Sugery Near

So I've dislocated my left shoulder 4 or 5 times in the last 9 months. I have been trying out for my local college's mens soccer team for 4 days doing pretty well basically guaranteeing a spot on the team, though most likely not starting. Day 5 of tryouts and my shoulder dislocated during scrimmage with absolutely NO contact....i was changing direction of sprint and flung my left arm up over my shoulder for momentum and out it went. This league is much more physical than high school. I am going through some basic PT right now but it worries me it comes out so easy. I am most likely going to tell the coach tomorrow morning that I am done and will schedule surgery. I love this sport and wanted 2 more years...anyone else have stories, advice, or wisdom for me? Thanks for listening.
