Fearing the unknown

How do you put fears aside? How can you get past them and move on? I SO wish I knew the answer to this. After a lifetime of criticism and being told I couldn't do things, I live a life of fear. Fear of success, fear of failure, fear of rejection......how am I supposed to lay aside those fears and do the things that God and my heart are telling me to do? I know, I know.....just give it to God and ask for strength. But I don't even believe in myself.....I DO believe in my ideas, which I think is a start. But pushing past the fears and putting stuff into action is another story totally. I have this block, I suppose, that if no one has ever believed in me, how can God possibly believe in me? I know He does, but someone tell me how I can drop this? I could probably already be a millionaire if I only took even half of the ideas I have and put them into place. I am smart, I am discerning (most of the time, anyway ), I am way creative, and I LOVE to learn....isn't that a good start for a recipe of success?! But how can I just let go of the stupid fear. I KNOW that not everyone is going to like me, or admire me, or agree with me, and honestly, I am pretty okay with that, BUT hearing rejecting words or crticism can shut me down instantly and make me run SO far from what I am trying to do, never to return...or possibly return but WAY down the line. Weird because ALL the avenues I am the strongest in revolve around criticism....people liking what you do, or NOT. I plead with the Almighty Savior to give me the strength I need to push me past this feeling of inadequacy and move me into the world of confidence......of no fear.....of success. People who criticise me.....go to.....ummmmm, well....I won't stoop to your level....Bless you, please find a life where your very being doesn't revolve around making others feel bad....because somehow, some way, I WILL get past this, and all I can say is WATCH OUT, MAN!!!!!!! Your over-inflated ego is gonna get popped when I come flying past you, and it will be a joy for me to watch you splatter onto the ground when you fall off your precious pedestal that you have placed yourself on......geez, I'm gonna go now and find some strength to conquer this fear......belle down unda, out!
