Some of us have become exhausted and anxious people pleasers who can never be liked enough; an anchor that some of us have been carrying around all our lives.
The simple truth in the matter is that no matter what you do and how you act between now and when you die, some people will not like you.
In this instance, it's not dislike because you've offended them intentionally in some way, I'm talking about when, for reasons best known to themselves, they just do not warm to you.
For your own sanity and happiness you simply need to be OK with that; it's very normal human behaviour.
If you want to take on a sleeping disorder then do not ask yourself questions such as: "Why don't they like me", "I don't think I've done anything to them?" Their dislike says more about them (their own unique perspective, their own thinking and their own issues) as opposed to what you have or have not done.
