How to love my self ?

You need to see yourself like God sees you. He thinks you look perfect. He set your DNA to do EXACTLY what its doing. The color of your hair, eyes, your height, your metabolism, etc. was designed by him. He made you the way he thought would make you look best! Look around you and count the people that look like you. Unless you're a twin or triplet or more, there won't be very many people. You are not something off an assembly line. You are a work of art designed by the Master himself. He knows every hair on your head, and every cell in your body. Now think about God. He created and sustained the universe. He created parts of space that men never have and never will see. He can shift the balance of this earth with just a single word. He can kill us all and bring us back to life as many times as he wants, whenever, wherever, and however he wants. He's more amazing than words can express. And He LOVES YOU. Now tell me, if this great and powerful creator of worlds loves you enough to spend THAT much time and effort on you, then don't you think you're worth some love?

loving yourself isn't something that happens over night and it does take time
however, if you believe you are fat [which i am sure you are not, people would not lie to you and if they are your friends and family who are telling you, i am definitely sure they are telling you the truth] having a boyfriend isn't the be all and end all! i am sure you are a wonderful person and are beautiful, perhaps you don't really put yourself out there as much as everyone else.
to have love in your life, you should love yourself first. here are some things that i have previously tried to help myself feel better in my own body -
- i have a reminder on my phone everyday, it tells me in the morning to feel good about how i look
- try looking in the mirror and instead of looking at your flaws, focus on things you like about yourself
- attempt to be more confident, stand tall and smile a lot - people will notice you more if you smile and people will more inclined to speak to someone who smiles
if you really want to see some changes in your body, then try toning up more, you probably don't need to lose any weight at all, but toning up and eating a little more healthier will make you feel better on the inside - drinking water also helps you feel better too
i hope this helps and you begin to feel better with yourself in the future :)
