if this physical problem is bothering you, then there are other
ways to improve your confidence...
few years back when i was stil in secondary school, i was also
having this same problem like you, but after working and starting
to earn some money, i gain other alternatives of confidence whereby
when i am rich, with a fat wallet, i am confident....
others imidate idols to be confident, others excel in sports to be
confident, if you find it hard to deal with this, then there are
always other ways whereby you can increase your confidence via
other ways...
look on the bright side...
think out of the box..
