It's not an argument. Something that makes one's life much harder compared to other people is not a blessing. A blessing, if such a thing actually exists would be something like being born with a crackerjack immune system of into a wealth family. What you have called a blessing is in fact burden that affects many areas of people's ability fulfil their potential. Telling someone to "stop worrying" rather than try to do the best that they can to fulfil their potential is simply mind blowing. That's like telling someone that they are powerless to change.
