Speech Blocks are ruining my life...

Speech Blocks are ruining my life... Got a call and I was unable to say my name. I hate being like this. I can talk and I have no issues regarding that but when it comes to saying my name, it's always a difficulty and today, I just froze. I just had to come up with an excuse when they said they couldn't hear me and I blamed it on the network. It felt really embarrassing and I feel like disappearing or just wanting to be nonexistent. I seriously hate this....
