Please i need help, but i am very jealous of my brother in law's wife. how do i get rid of these feelings?

Just take a deep breath in the fresh air and say I am ready to face any situation whatever may happen in life, I will be fix and happy for anyone. I know you will find this ridiculous but sound verygood indeed. Always keep a smile on your face and never think wrong about anyone and you are surely to become the most beautiful as a companion or bride and for the afterwards. Life is simple and we are the one who complicate it and found ourselves in quite similar problem. You always remain shiny and no one or nothing is greater than believe in you are capable to face all dificulties.
