I believe everyone has gone through particular times in life where you feel less of yourself, rejected, dissapointed by those you love etc and you find yourself not believing in you anymore and letting situations and people define you and so on.
I just wanna say, that shouldn't be the case because God loves you so very much and you are who He says you are; A chosen generation, a royal priesthood, a perculiar person, a holy nation (1 Pet 2:9) and alot more that the Good Book(The Bible) says, which is the Word of God and that is God. So do not believe anything or anyone that defines you less of what God says you are. You are the best version of you, so never look down on yourself because God never looks down on you
*Believe and Love God, believe and love yourself, and believe you are His and watch all that negativity fade away completely. God Bless
