Hello "strong",
1st off, you chose a good user name, the reason why I say that is because it must of took couragious and strong willed to standup and give your presentation, knowing how low you fealt and how self-consious you are about the sound of your speach due to your profound problems with your hearing. You should be proud of yourself for standing up and following through on your objective, maybe some of your class mates didn't fully understand what you were converse, you gave it your best shot you should be proud of that acheivement, that's all anyone can as of you.
If you feel some of your friends and classmates didn't appreciate your contribution and hard work then they are not worth knowing they can't see past their narrow mind set, which is a fault iin todays society and the way its run. Lack of support and understanding of HOH/D portion of todays society.
How are you getting on with your speach therapy, I wish you every success in your speach therapy, I know you will do well ! There are so many people out their who understand and want to help.
I also believe that learning ASL and continuing speach is the positive way forward.
Keep in-touch, all the best to you.
Kev
