To not do the thing you feel you were meant to do, to not share your truth is painful. It hurts to hold something in when it wants to grow and reach people.
And to let fear stop you is insult to injury; now you aren't just feeling repressed, you are feeling fear.
Fear will stop us whenever we let it. It tells a sweet lie too. It says that if we follow its orders we will stay safe and secure. But fear can't keep us safe (unless we are in a real immediate life or death situation where we need the adrenaline to "run" or "fight").
Security is an illusion and given the latest research, living in chronic fear is bad enough for your health that the one thing we can say confidently is "living in fear is UNSAFE."
I know from experience that saying what matters to you and doing what you believe you are called to do is the scariest thing, right up until you do it.
Then you're like, "oh! I don't know what I was so scared of! That felt great!"
Unless you are like, "Umm, I have terrible B.O. from sweatin' my ass off for the past 5 hours leading up to that conversation. Now, I have to go bathe and take a quaalude. ...But I don't know why I made such a big deal out of that. It wasn't so bad."
Or you're like, "Oh MY GODD!!!! I just DID IT!! I DID IT!! I SAID IT!!!! SOMEONE GIVE ME A HIGH FIVE RIGHT NOW!!!!"""
Any way, don't let fear and the illusion of security stop you from being authentic and doing what you were meant to do, because looking back mostly you will just wonder why you spent so much time waiting.
