I think if you want to feel, “This is exactly what I’ve been wishing for” then you should focus all your attention on those things that you are wishing for, all those things that you want, and stop letting your best friend’s life take up rent in your head. Focus on you, not her. Think of ways you can achieve what you want. Then go for it. Jealousy is normal, so it’s okay to feel that way. Just don’t obsess over it – obsess over you because you deserve all the things you want in life. When you start focusing on you, things will get better.
