How do I get past this feeling?

I am sorry to say that most people really don't nowadays. It's like people are getting worse.

Yet, the challenge is not being one of the cruel and rude and bad even when you feel you've got no one in your corner.

Sometimes goodness will be taken advantage of.

I'm not saying this depress you. But it would help if your validation would come from inside and not outside. Keep you in tact. Rely on God. And along the way as you learn to be your own confident self, hopefully the right people to keep with you would come along.
