Hello, I'd like to help you with your question.
It sounds like you are doing all the right things in order to make friends and get along with your family. However, you are not getting the reaction you expect from these other people.
You seem to be doing fine with how you interact with others. You are socially involved and seem to be achieving what you want to achieve. So it does not sound like anything you are doing. That leaves the kind of people you are interacting with as the issue.
With family, issues usually are caused by past history or the stress
of a current situation. Disagreements with family are very common. But if you have no conflicts with your sister or children, then most likely it is some type of perception on their part that is causing the issues. Try talking with your children about why they react as they do. Then suggest that even though they are busy, what can you do to keep in touch and improve your communication.
With friends and co workers, it may be more complicated. People tend to view others with their own issues in the way. So if you live and work around people who are unhappy as a group or have a certain set of expectations, they may be putting those expectations on you. For example, living in a higher income neighborhood is a different experience than a middle class neighborhood. The expectations on behavior of the "group" is different for each set of people.
If you look at the situation and still cannot find an explanation, then you may need to find untraditional ways to make friends and develop social supports. On line forums with others who have similar interests, pen pals, joining different groups and church are all ways to meet different types of people and broaden your social circle.
You can also ask others who you trust for input about ways to improve. Be open to the responses and do your best to incorporate the suggestions into your life. Sometimes someone else's view can help you see things you were not aware of.
I hope this has helped you,
