I work in public administration (office work). I have to communicate a lot. People around me know that sometimes I make some unusual delays and noises. But it doesn't mean I can't do my job. As for your post... >I m also sick and tired of holding back, not giving answers in class that i know really well. Not asking questions in classes. In fact i dont speak at all in my classes. Im struggling in disguise right now. Seeing me from the outside , it seems im a really happy person but deep inside im just empty and feel depressed. This is all somehing you'll have to address, regardless of career path. Do you have anyone to share these things with? Because carrying it around on your own most likely isn't healthy.
