Listen here, don't blame your insecurities, doubts and regrets on being human.
Get a grip of yourself and start changing if you have the power to write all of those things. Some things can't be changed, but you can start on working your attitude of blaming being human for your mistakes. Go work on your weak personality first. You are supposed to learn from the mistakes you make. If you keep repeating the same mistakes,
you are not human yet

The world isn't as bad as you think.
