On your learning to communicate, you also have to allow yourself a few bumbles now and then too. I used to be SO hard on myself I'd shut down and "hide inside", getting nothing at all done. Be kind to yourself, no one is perfect at being human.
This is what happened to me here at this lovely website when I interned here. It doesn't do your team any good to shut down like that. I realize this now, but when it was happening I was defeated. This is a good reminder for me and an encouragement.
I have this tendency and only recently I have been able to get some control back. It takes time but even a little improvement matters.
