Ignorant coaches assistant is making me regret coming back to the sport.

So basically, my dad passed in early December and this is one of my first practices back after being off for all of December and most of January (basically 2 months away).

It started off like a normal practice, and then we get out of the pool to get the main set, the coaches assistant says to me while the coach is explaining “it’s a pity your dad couldn’t have died a little later to save you from this practice” and I was really upset and angry about it so I told her to po and I walked out. In fact, I didn’t even get properly changed. I walked out wearing a towel and my solar briefs still on underneath because I was just disgusted with what I had heard.

My mum has rang the coach, and she’s complained about the assistant coach to him. I just don’t know what to do, after the break, I finally felt ready to go back to somewhat normality and now this lady has made me feel like I need another while off, or even a switch of teams for a while if not permanently as long as she is there because I feel like if I go back and see her again I might end up saying something I’ll regret. Fingers crossed she gets fired or something.
