Be careful who you surround yourself with
In life besides love it is very important to have friends. They make us laugh, have fun with and raise us up. Sometimes just to have a friend we will be friends with anybody, even friends who bring us down. That is wrong.
If you have a friend and they are constantly making you feel insecure than those are the wrong friends. If they say your ugly or make you feel that no guy would ever be into you, than they are toxic friends.
If you have a friend like that those are the wrong people to be around. You may feel that a bad friend is better than none but that is wrong. If you have one good friend that's all you need.
Sooner or later their comments will catch up to you. When they are not around anymore, you will have scars of insecurity because of all the lies that they put in your head.
If you have a friend like that talk to them and if they don't change then drop them. Build yourself up and wait for the right friend. Surround yourself with people who bring you up and not pull you down. Those are the people that are essential in life. Don't ever let anyone make you feel that you don't deserve what you want.
