Hello C2015: I'm sorry you're feeling so unimportant. Kids can be really thoughtless. I recall once, many years ago now, my brother-in-law's daughter looked at me over dinner & pronounced: "You're fat!" (Actually I wasn't particularly I didn't think... maybe a bit on the heavy side. But, in her eyes, I guess I looked fat.) Anyway... with kids... I think one just has to let it go. They're kids. They probably don't even think about what they're saying.

Adults, of course, are a different matter. With adults I think, if they're saying things that hurt your feelings, you certainly have the right to tell them so, if you feel you can. To some extent, this becomes a matter of boundaries. You have the right to establish & enforce personal boundaries... what you will & won't tolerate from people. California therapist Kati Morton, who uploads mental health related videos onto her YouTube channel, uploaded a video recently where she talked about establishing & enforcing boundaries. If you were able to go to Kati's YouTube channel & find that video, you might find what she said to be of benefit.

As far as what to do with how you feel about what family members have said to you, this is of course another matter. If you have the benefit of seeing a therapist, these are good things to discuss with that person. You can certainly post, here on PC, with regard to what has been said & how it made you feel. Sometimes just writing about such things can help. Journaling might be another option. There are also practices, such as those taught in the Buddhist tradition (e.g. compassionate abiding), for handling how one feels about such things. However, this becomes a more complicated subject. You could, however, look into some of this if it was of interest. I wish you well...
