I probably shouldn't post this but...
What do you need to get off your chest?
I feel a bit nervous about this issue.
I understand sharing things can be scary. If something has been bothering you, it isn't good to keep it private and hidden from others as it can lead to stress and other emotional problems. You should be comfortable sharing things with people that you trust in order to get the help and support you need to work through whatever issue is bothering you.
I think it's best to keep things to yourself.
There's nothing wrong with being nervous, but it seems like you want to share. Sometimes being vulnerable is hard, but it can really help when we have things that bother us. You have to let other people help you.
