Hi @LostAngel
I think the way we communicate with people has a huge effect on the responses we receive from them. It seems almost like emotional mechanics between humans. I believe that even the most balanced people will react negatively to negative emotions coming at them, even if only on the inside. This is the case even with the ones we most love and who also love us the most.
I have hurt people I've loved enormously when expressing my feelings, frustrations and sufferings in ways that directed anger at them. Looking back I see now that I was actually abusing them verbally and emotionally. Ironic, given that I felt myself fully the victim of my circumstances. When in pain and feeling very weak in ourselves, we sometimes forget how much power we have in relation to loved ones, how much we can hurt them.
Directing my anger and frustration at people I loved has also only brought me more suffering than I already had, the opposite of what I wanted and needed, just as hurting them was the last thing I intended to do.
With the help of my medical support professionals I have mostly overcome this over time, though I still feel angry easily and must take my medications or it can again become a problem for me and those around me, though fortunately not usually anywhere near as badly as it was.
All this is my experience and I do not know the specifics of your situation. I guess I just agree with you that being kind and loving to others tends to bring the same back to us. So anything you can do to express yourself to family in calmer ways is likely to help you too in the long run.
