Yes, I am semi-new still and feel the same as you. I tend to not "share" as much here yet. It's hard, but I certainly do feel as though I want to chime in on other's issues. Maybe because I can tell these are good people, struggling and it hurts me tremendously to see that across the world (and these members are everywhere).
I find it easier to console others and truly feel genuine care for them when I read about their struggles. I don't do this so well for myself, but hearing what others are facing inspire me to live better and heal myself. There are some incredible stories here (and sad) and how people live on is an incredible booster for me to keep on as well.
Don't feel like you have nothing to give, you don't have to share, if you feel something to say and want to post, then go for it. It will be met with welcoming people here.
