One friend is better than 10 fake ones
When you are young being popular can mean a lot. You may even stay friends with people who hurt you. What you don't realize is that these people are bringing you down. They will keep bringing you down.
If you are around negative people take some time out. First be your own best friend. Do affirmations or whatever it is to make yourself feel good. Be your own best friend.
Join groups and be friendly. Don't expect right away to have the perfect friend. Get to know someone and take it from there.
If you find yourself one good friend consider yourself lucky. Be thankful for that person and more good people will follow. Another thing is treat others how you would want to be treated.
