Hey! I had the same problem for the longest time. I just couldn't love myself or believe that i was important...and i felt like people who said they loved me were lying because i wasn't good enough to be loved. Here's a god verse.
PSalm 139:13-16
13-16 Oh yes, you shaped me first inside, then out; you formed me in my mother's womb. I thank you, High God—you're breathtaking! Body and soul, I am marvelously made! I worship in adoration—what a creation! You know me inside and out, you know every bone in my body; You know exactly how I was made, bit by bit, how I was sculpted from nothing into something. Like an open book, you watched me grow from conception to birth; all the stages of my life were spread out before you, The days of my life all prepared before I'd even lived one day.
God loves you for who you are. Genesis 9:6
... Because God made humans in his image reflecting God's very nature. You're here to bear fruit, reproduce, lavish life on the Earth, live bountifully!"
He loves you so much that He chose that your life be saved over His own son's! John 3:16-18 16-18"This is how much God loved the world: He gave his Son, his one and only Son. And this is why: so that no one need be destroyed; by believing in him, anyone can have a whole and lasting life. God didn't go to all the trouble of sending his Son merely to point an accusing finger, telling the world how bad it was. He came to help, to put the world right again. Anyone who trusts in him is acquitted; anyone who refuses to trust him has long since been under the death sentence without knowing it. And why? Because of that person's failure to believe in the one-of-a-kind Son of God when introduced to him."
God has big plans for you...plans that you on your own without faith could never even imagine. Jeremiah 29:11 11 For I know the plans I have for you," declares the LORD, "plans to prosper you and not to harm you, plans to give you hope and a future."
You are just as beautiful and important as anyone else on this earth. God says he formed you inside first. Then outside. You can't take your body with you to Heaven. What matters is where your heart is.We all want to look nice and/or cool or whatever (especially me!) but in the end, thats not what maters. What matters is that we choose to accept Christ's love for us, and then love others. in order to love others, we must love ourselves. This won't happen over night...it takes time. But every day you must choose to believe the truth that Jesus Christ loves you more than anyone else. And ill guarantee you that there are people all around you who love you ... for you! God bless you!
