I know exactly how you feel...Although I've only just begun to be able to start sharing my thoughts by sharing my situation with other people on this forum so I can't really provide any insight or help...

The only person that I provided any hint of my issues is with my brother. He told me to get over my problems and get on with my life. Only if it was as easy as he said...He doesn't bother to understand how hard this is for me and how much it affects me. I already put up a shell as you said like a "happy face" as to hide my problems from everyone and that makes me just reinforce it even more...I feel like it is easy for people to judge us and tell us to cheer up and get over it. They just don't understand how hard it is for us.

I wish you the best of luck and hope we both can see the light at the end of the tunnel sometime soon...
