Drowning in misfortune after misfortune

Hi, I came across this forum. I'm at a complete loss right now... almost to the point of being numb. I thought I could get some help and hear other others experiences.

This year has been a complete rollercoaster. For context about my situation, im in my early 20s and last year I was living at home with my parents, studying at university straight out of highschool.

Several things have happened since the beginning this year in order:

Lingering trouble with a father who emotionally and borderline physically abuses my mother. He manipulates the situation to better suit his reality and inflated ego. He has thrown hot food and kitchen utensils at my mother before, and it got to the point where my mother was considering divorce.

Moving out from home for the first time with boyfriend of 6 months. It was fine in the beginning, until issues outside of the relationship such as mywork, covid and family financial hardships caused issues. He was unable to offer emotional support and often left me crying until early morning. and I felt more alone than ever, even while sleeping besides him.

Starting work in healthcare at the climax of coronavirus in an unsupportive, clique workplace caused associated emotions of incompetency. I also felt isolated because I couldn't visit my mother and brother because I would be potentially putting family at risk, leading to first time experiencing such physical distance and isolation from family.

I also lost connection with friendships and my supporr group due to friends moving away for work

After 1 year of living together, discovering boyfriend was emotionally cheating with other girls. He said she was better to talk to because she didn't ask so many questions. While working through first instance, finding out he was continuing to talk to/give money to other girls

Broke up with boyfriend but continuing to live in same area, moving in with a friend for my career but spending more time at home with family and attempting to rebuild relationship with family

Then as I was gaining footing, I discovered my father had been cheating on mother with a woman for 10 years+. I don't want to tell my family because I don't want to break it apart as it was just starting to come together, but I'm being torn apart holding it in

I am feeling completely overwhelmed and looking for advice/where to go from here/past experiences.

I haven't been able to sleep properly or eat because I'm assuming I've been too much on edge.

I be seeking professional help but I need to sort out my work schedule (working almost 7 days a week)

Thank you
