Well said!

You can look that up on youtube. Yes it's easier to learn if someone shows you, but youtube is quite good too.

You probably already thought about this but did you try to superglue those shoes/sneakers together?

Ah I am sorry, that's difficult then.

Yes so did I when I was teenager. Only my dad worked and we were big family. It could take months of asking to be taken for new shoes. I was eldest so there wasn't choice wearing handmedowns from my siblings. Could perhaps any of your cousins lend you pair of shoes?

I am sorry. Blisters are awful. This is weird advice but make sure that you are not bending your toes wrong way because it will damage your tendons in them and will cause you pain when you are older. I literally can't find comfortable shoes and every step is painful

I am so sorry this is happening to you. I remember wearing too small shoes as a kid for months. Awful pain.
