From the error you posted I would guess you've got some sort of missing mysql dependency.

    _mysql.c:44:10: fatal error: my_config.h: No such file or directory
       44 | #include "my_config.h"
          |          ^~~~~~~~~~~~~

Looking at the github page for mysqlclient maybe you could try running:

sudo apt-get install python3-dev default-libmysqlclient-dev build-essential

In my experience, missing a .h file generally means there's a development library missing from your computer that the python extension needs
