You can withstand it.

The ones that really care for you will always be there through hard and easy times. Nearly no matter what; if you mess up, they'll be there to help you. If they need help, you bet your ass you better be there to aid them. If your friend is no longer over such a small thing after being through so much, it's no use being anything close to them. If they can't get past something you once did, accident or not, they do not deserve to be near such a good person that you are. All that they will be doing for them self is remove one perfectly good person from their life. All that they should have left onto you was a smirk on your face because it proves only that they are not as intelligent as you are and that they cannot work out problems and must run from them. You cannot allow the people that enter and leave your life keep you down. Allowing this to effect you will do nothing but slow you down. Let no one run your world. You will move on. You will find success no matter what's the cost; if you need to loose all your friends, or if you need to drop one friend. You will forget about them in time.
