Many Doctors, Dentists ect, would disagree with you, as would I. It can often be more harmful to help yourself, instead of letting go of your pride and asking for help.
Now I'm not going to say that help is a one way street. But you can heal a lot faster if you yourself want to be helped. You should always remember that it is no great shame to want someone elses help. And it's no great shame to accept help that's offered.
Humans by the laws of nature are social creatures. We do are very best at helping others while being helped ourselves. If there is a problem we can't fix on our own then we turn to someone else and ask them to fix it. Emmotional damages are no different, it just shortens the list of people who can really help you.
Also I would avoid lastwar's addvice. You can keep your cool as much as you like for as long as you want but it doesn't mean that everythings going to go the way you want it too .
