You have no second thoughts when come to your part in lending a hand helping others in need. You will sacrifice what you have and with passion you will not retaliate on whatsoever the outcome when you have made your decision.
That will be nicely said than done. The problem is you are not them. It is not easy to get any help when come to your turn. Unfortunately, it also applies to your friend and maybe your claimed to be "best friend".
Then you will feel very hurt and lost. It will be worst if you start to do the same as them when another cry for help pass your path.
I learned that, if I wish to help or lend a hand or sharing my experience it is because I want to do it and may god bless me. Period.
