AIO Crashing Out infront of Family

so

im not very close to my family and siblings. im used to let them know about my life in a very superficial way because well.......... we are very dysfunctional and we judge each other at every opportunity. so i work a very very demanding stressful job and one day i woke up at 3 am to go to office to finish some of the workload i had because it was getting stressful and i wanted to be done with it. on the same day, we had a very late family gathering and i was gonna bail on it because i was awake working all that day. anyways.my mom guilt tripped me into coming and i did. i obviously looked very tired and couldnt engage in any conversation. they kept nagging on me and asking questions about work to the point where i actually crashed out. i started getting so emotional about work and stuff and my brother asked me a question about work mid way and i told him whats the point of u knowing that fact now. he felt offended and started to yell at me and telling everyone to not interact with me because im crazy and thats all i do. he started to yell that he wanted to help me out etc...

the whole point is that i just feel so cringed out at myself for crashing out infront of them and actually burning myself out that day.

i still feel embarrassed by me being emotional infront of them. and i just hate this.
