You are beautiful no matter what people say. You should be as honoured and thankful to be living this life regardless how much pain you go through. This life is wonderful, you are wonderful. It does not matter what you look like, what size you are, what colour you are or who you are, you are beautiful.
Being skinny is not important what so ever because as long as you are healthy, that is all that matters. If you’re trying to gain attraction from people, don’t because you’re only gonna attract ones that only are interested in your body what you own, not care about you. The only people it is worth attracting is those you don’t even need to attract because those who care for you will see you as beautiful what ever your size and they won’t be attracted because your body, they’ll be attracted because of who you are, and surely you’d much prefer that?
No matter how small or large you make a difference, remember, you are still changing the world. Often or not it takes the little things to make a huge difference. Just one few second hug could change a whole life. Just one £/$/€(etc) donated to a charity could be enough to save a life.
Make the most of each day, always look at things positively. If something doesn’t go right, don’t worry, keep trying because the only time you fail is if you give up. Be happy what you’ve got, don’t compare because what is important is who you are. Always be hopeful. Success only comes to those who try.
