I've slowly started checking out at work

I've been noticing a pattern recently with me. My personal life is kind of going downhill due to a lot of stuff I had to face within a short term like the death of a family member, dad losing his job (I luckily have mine) and all of this is slowly eating into my work performance.

I feel like I've started not caring about deadlines and stuff at work and this is slowly raising concerns from my manager. It's like I've checked out pretty much and I don't want to enter this dangerous path since my family is kind of dependant on me and sometimes I also have an existential dread about what's the point of all this.

Do you guys have any advice to deal with this. I haven't let it affect my performance much only by a little so I can still be salvaged and my social skills are dwindling as well half the time I'm in stress about my personal life which I won't be able to solve and is dependant on other people and just life circumstances
