Sometimes the load is more than the rock can bare

Ok let me apologize in advance for my spelling and punctuation. Sorry 

I have always been the rock in my family. Even as a kid my sister’s leaned on me. Being the only boy I was there safe place. Then I got married and had kids and became the rock for my family. Fast forward to 4 years  ago my girls were 19 and 12 and were in a car accident the truck rolled 4 times.  My youngest was thrown from the truck. Broken neck and  numerous other injuries. After 6 months in the icu and several surgeries the months  of rehab she is back to her beautiful kind self. But during that time we find out my wife has chronic heart failure. So it’s back and forth to the hospital on a monthly basis. Keep in mind it 2 1/2 hr to a decent hospital. They put in a pacemaker get her on meds and we think we are in the clear. Move forward another year thing’s seem to be settling down meds are working just have to make regular visits to Dr. Life says ok deal with this. Stage 4  Metastatic breast cancer that spread to the brain lungs and limp nods. So chemo radiation and a years worth of back and forth to the Dr thing start to look up cancer treatment is going good we think she is going to beat it. Remember the heart failure we’ll the chemo and radiation took her heart from 50% function to 15% now we are back to spending more time in the hospital than we do with our children and grandchild. My wife passed on February 3 2023 from a heart attack. I may have been the rock for all these years. But she is what kept me stable. I am fractured broken I find it hard every day to deal with every day life things that have never bothered me before have me stressed out. The last week has been rough I don’t want to leave the house. I have always been the strong one nothing got to me. Heart of stone something had to be really bad before I was emotional. No it seems all I can do to keep it in but I have to for my girls. So my question is what does the rock do when the load becomes to much too bear?
