It sounds like you have a good imagination, but one that might run away with you sometimes and have you thinking about future possibilities instead of present situations. We only have the present in which to live; when we "worry" it is usually always about the future and we can't know the future.

Projecting what others are going to do in the future (not like/love you or make fun of you for expressing your opinion or having a viewpoint not the same as theirs) is even more of a problem because we often don't know those people very well (so why care what they think?) if at all, presently, so then trying to do future thinking with such non-existent people gets even more dicey!

Stay with only yourself and only in the present and I think you will feel a lot more comfortable. Yes, you can imagine what it will be like to change your point of view or beliefs in the future but leave other people and their feelings out of it! Other people can't make us feel one way or another; that's all our own background and experiences and thoughts coming from inside us, not out there.
