I often regret sharing good things happening to me with others

I rarely even tell anyone about anything in my life, good or bad. I think I kinda came to the realization at a young age that nobody really cares about your life, many people just care for themselves and that's all. When bad things were happening in my life the only person to help me was my mom, but others, they couldn't care less.

If something in your life is good and you tell someone, they might get jealous or envious and wish bad things for you, I'm kinda big on privacy and protecting my peace so I don't even let people know anything anymore.

Like regret in what way?

The same people who judge you for all the bad things that happen in your life are often the same people who aren't happy when something good does happen to you. So I don't care to share anymore, unless I'm really close to them.

it ultimately depends on the person who you are sharing it with right?

if they can't be happy for you or if they become jealous or something that maybe it's them showing their true colours???

never really had a problem with that

It really depends on how they react, sometimes if they don't seem happy about your news it can ruin your own happiness
