Check your response towards your mom since you believe that you are the disliked one. Find out how you respond. Is your response endorsing your pre-existing belief? This belief sets in early in childhood after experiencing seemingly bizarre negligence on the part of your mom but once the perception turns into belief your response to that belief perpetuates further dislike. Be sure you are not in this loop. Check out whether you can break this loop or not.
What is important as an adult is you liking your self. Give yourself what you expect from the world.
