Thanks for your responses. I was wondering why they would act like this.
So some don't care, don't know what to do, are unable to cope and are immature. Sometimes it just feels mean or like bullying (immature).
I learned to ignore it in the past when I was doing much better. The laughter seems to have come back now that I am not so well. A couple family members who had their own experiences and grew are more understanding now.
