jealous: I am an adult, but unfortunately still succumb to petty envy. My family buys my adult sister things all the time but can't really help me out when I need it.

I know it's very petty of me but it is starting to bug me. My family has been very generous towards my adult sister as of late but have not really paid much attention to me.

Have you tried talking to them about this?

This has happened on and off for years, and I always try to talk to them. I usually get no response. It's led me to be self-sufficient fortunately.

That's really frustrating, they'll realize only when you start distancing yourself from them
human
I have in the past and it didn't seem to work. I'm hopeful they will open up to me one day though.
