Dungeons and Dragons DM/GM questions!

I LOVE DUNGEONS AND DRAGONS!!

This is my drawing of my personal character.

Arthana Elikilia - Half-elf Ranger

I have played a home brew campaign with a few friends and we all just recently started a new one! Back to level THREE!! 🤗 So exciting!

But i have been looking into DM/GM my own campaign!

Now, i have a lot of hours racked up playing a playable character in the game but never running one!

Super nervous!

So i want to know what you guys would suggest to do to get over some of these nerves and to take the leap into DM/GM my own campaign???
