Remember, Allah (swt) has chosen everything in your life for you, your body, your friends, your family. So the family that we are given are best for us, whether we see it or not. Therefore, it's our duty to respect and cherish what Allah (swt) has given us.
There are times, when this becomes to difficult. In such times, look to the hadith of the Prophet (saw):
Abu Hurayra said, "A man came to the Prophet, may Allah bless him and grant him peace, and said, 'Messenger of Allah! I have relatives with whom I maintain ties while they cut me off. I am good to them while they are bad to me. They behave foolishly towards me while I am forbearing towards them.' The Prophet said, 'If things are as you said, it is as if you were putting hot ashes on them and you will not lack a supporter against them from Allah as long as you continue to do that.'"This advice I give to myself because I know I can be a better person to relatives who are not the best to me. The rest is up to Allah (swt).
Until next time...
