Beating yourself up mentally has the opposite effect

Being hard on yourself mentally has the opposite effect. Beating your self up doesn't push you harder, it keeps you stuck. The bully in your head convinces you that you are worthless or that it's pointless. So why even try to make a positive change? Beating yourself up mentally lets you off the hook to grow emotionally and intellectually. 

You are not perfect. No one is. Realizing this could potentially let you know that you are going to make mistakes, you will fear things. You are human after all.  You are worthy enough to make change in your life. It will not only make you happier, but it will make those around you happier. Try using encouragement instead of discouragement to help yourself along the way in becoming a better person.

If you find that you need additional help, seek out group therapy or individual therapy and allow a therapist to guide you in the right direction.
