It is often said the nobody can make us happy, nobody can make us sad.....to be happy or sad is a choice we can only make for ourselves.
When times are good..be happy for yourself...when times are bad, be happy in the knowlege that many people are worse off than you.
You are young, attractive and intelligent, be patient, this part of your life will pass...have confidence in yourself.
And if you want someone to talk to, we here will always listen
Best wishes...David
