I get very angry when people forget we (well you all) are humans first. I'm just a frog of little brain so I don't count myself among the "we". Who you are or what you do is your business not theirs.
People are so quick to judge without the slightest idea of the hurt they are inflicting. Only small people inflict pain on others with their words.
I would be confined to my lily pad for a month if my mother heard me say this. But the fact is think of yourself first. Do the things you like to do, think the things you like to think. You can be anything you want to be.
Not having a girlfriend is not the end of the world. If fact there are a lot of male humans who rue the day they decided to ask a girl to be a "girlfriend."
I wish you the best and have faith that you will over come you problems with self-esteem.
