Hair loss in the middle part PLEASE HELP

I’ve never bleached my hair and I’m still very young. I’ve had my hair parted in the middle for the longest and did many hairstyles with it like this. I recently changed it to a side part then when I wanted to change it back to the middle part I noticed a huge amount of hair loss compared to the other parts of my hair. Please help, what should I do to have it grow back. Im guessing it’s the stress I put on it doing tight hairstyles on the part but I’m not sure.
