Lost my Dad, Aunt and Uncle in the space of 7 months

I lost my dear Dad to cancer last November, one of my uncles 3 weeks ago and one of my aunts to cancer last week. I’ve continued to go to work and carry on with my life between now and when my uncle passed away but everything feels really heavy and I don’t know if things will get better. Sometimes I have good days, sometimes I have bad days and other times I feel like I’m about to cry and that nothing matters. I don’t know how much pain I can take, given that I’ve had multiple losses over the past 5 years
