How to get over this?

The feeling of sadness when your favorite is being attacked online and you feel inclined to defend them online. I get really upset when I see any bad comment or false rumors about them being talked about.

It's very draining..I feel like I want to protect them even though they probably have lawyers and access to PR firms.

I work, I have my family and I have a very close friend and we speak daily. Why do I still get too attached like that?!

When I shared with my friend I have a celebrity crush and told her how come she doesn't have one, she said in essence that she doesn't get too deep into those things cause it feels pointless, since she will never get to meet them. I know I won't either, so why don't I have the same self control?
