I am trying to find a word someone who ridicules someone else's feelings. When I say generally anything, they'll say something completely unnecessary (and usually hurtful). Most of the time, I am not even talking to them; they just jump into the conversation for no apparent nor helpful reason.
For example, if I say that I have my shoulder hurts, and they will scoff, thinking I am being fake and/or trying to get attention (which I never do; that's weird). There are also general instances where I will say that I don't like a certain food, and they will scoff and say that I always try to find something to complain about.
I also would like the verb form of what they are doing. For example: "This person _____(s) my feelings." I'm not sure if the word "belittle" is the right verb, but I hope you understand what I mean.
