Growth actually requires us to move through fear and therefore discomfort. When we are in the process of growing, especially when we're at a tipping point, discomfort, negative feelings, negative emotions, anxiety, random illnesses, etc always seem to crop up. I noticed myself feeling a little negative, tired, anxious, sad, stressed, unreasonably angry about nothing really. This type of cycle used to make me lash out, or just decide to give up or take a break from living my life in a way. And I'm not going to lie, it started to take me out. But I remind myself that I have a choice in what I make things mean and I have a choice of how I will react, and whether I will give up and go back into my "safe, comfy box" or keep following the callings of my soul. I've learned all too well, that when I go for immediate comfort over my soul's calling, I end up more miserable in the end until the discomfort of staying "safe" becomes too much to take. Thennnnn I finally make the changes or do the things I KNEW my Soul had wanted me to way back when I decided to check out.
my point is, if you're called to do something, and you doing it, and then you get uncomfortable and fearful, remind yourself that it's part of life NOT a sign to quit. Negative emotions WILL happen so just let them be there. Use them as a sign that you're freakin living you life!!
