Never change yourself!
You are perfect the way you are because this is how the almighty planned things for you. He can never be wrong. So, you're absolutely fine. Things don't work out according to us 'coz they were never meant to. We should embrace whatever we are blessed with. We should embrace all the things & people who once held or still hold an important place in our heart.
That's the best thing we can do to ourselves and others too.
