I lost my fear of public speaking.

I lost my fear of public speaking. Hey guys, a while ago I decided to face any situation with my head held high. Now I order food, answer calls, go shopping, and sometimes even make video calls. All of this has helped a lot; I've noticed a slight improvement in my communication skills, but it's not enough to have a conversation about anything, since I still get tongue-tied... What do you recommend? Should I keep doing this to cope with situations? What's your advice?
