Well as someone that always try to be kind and care about people lot, I undesrstand your situation a bit. Caring or being kind is not a weakness, but reality is that your kindness won’t always be responded with kindness, and you will get hurt a lot by people because of it, but that doesn’t make it a weakness, you just have to understand that people will act according to their own beliefs and experiences, and that you can only control your own actions, but please if I must say, don’t stop being kind and caring, to do that is a strenght, at least for me.

I think talking with your parents about your worries and emotions is the right thing to do, but even if it doesn’t go the way you want, always remember you can only control your own actions, and your actions is the only thing you should fell responsible for, sometimes you will still fell bad for other people actions, but you should try to always keep that on your mind.

I hope I could be of help, have a nice day.
