I think just smile and distance yourself for a while get your head together and let tempers fray. Your family will apologise as they will feel terrible about what they said.
And if they don't then I am afraid you need to study hard and keep being driven never give up and get the goals you want.
Depression is hard for not normal people to understand (non depressed people) so they don't know how you feel how little things become big things how you overthink everything and need to get constant reassurance on the slightest of decisions.
Negativeness is a depressed persons worst nightmare we need positives in our life be it a friend or online games or music. A dog helps depression and even walking a neighbours dog for free will give you a little bit of love and happiness as my neighbours dog gets long walks now and then by me and always scratches my flat door to talk to me.
Forget what they said and never speak to others like they did to you. Be the bigger man.
Talk to specialist they will know what to give you so comments like that will breeze past you.
Goodluck
