I also feel the sane as you at first but i scared that i will regret if i leave SFI and due to i strongly believe in SFI, i decide to stay. With strongly encouragenent and motivation from my upline, i feel my spirit come again to move forward in SFI.
My advise is think it before u make a decision to leave SFI. Give yourself a chance to learn more and get help from your upline to guide you. Don't give up!!! Keep it up.
