Hair growth problems??

Sierra

So when I was younger my hair used to be a little bit above my shoulders or just a little bit past that but the I went swimming every day and my hair started to break off. I have About 3C/4a hair that is very short. I have a lot of breakage in the middle and there’s barely any hair there. Please give me advice, hair tips, you tubers, etc. Being in high school with short hair is very depressing for me☹️.

Here are some old photos of me that show my hair length.

Here’s some to show my texture (it changed over the few months now it’s a little bit looser)
