Need some advice

Here is my dilemma. The first time I went to college in the early '90s my grades were absolutely terrible. Not because I couldn't do the work, but because I was very immature and treated college like a three year parent sponsored party. Now, that I am much older I am finally going to try to realize my dream of becoming an RN. The problem is that even though I am back in school and taking prerequisites, I still have to submit those transcripts from many years ago. Frankly, I am embarrased to send them anywhere but I know that If I don't some way , some how that will catch up with me. I need some encouragement because right now I am starting to tell myself that I should just forget it because with a transcript like that no one is going to consider me. Has anyone been in this situation and if so how did you handle it? Thanks
