What do you do when you have been the “Family Manager” and all around “Caregiver “ for your family and now no one is speaking to you?

I took care of our Mother in my home for 8 years, with a sitter while I worked a full time job. Siblings only stopped by when they had nothing else to do. All at my expense, no problem!
My oldest sister is 80 and was living in assisted living, a bad situation. She agreed that she wanted to move in with me, I had plenty of room. I visited her every day the year at AL, other sister visited 3 times in a year.
My son (my only child) lives with me since my husband passed a few years ago.
My health is actually worse than my sisters and I’m 78 years old. The youngest sister is not a hands on person, for no one! I’m the middle girl!We made the move, putting her things in storage, that she didn’t need. The other sister insisted on taking everything to Goodwill, but all her furniture are beautiful antiques. I was the one having to do all the work so I stored them.
After a few weeks, with me getting only 3 hours of sleep each night, things started changing. She became verbally abusive, throwing her plate of food at me during meal time, getting up during the night to cook or wash clothes. She would turn the stove on and go back to bed.
I had to lock all medication up because she would take anything she could find. She would run into my fur babies with her walker…you don’t mistreat my animals!
She was verbally abusive to my son…just horrible. She would put her wet diapers anywhere, hide them! My son would always take them to the outside waste bin when he was aware of the need.
Finally, dealing with my illnesses my doctor ordered me to bedrest to get off my feet and legs. That was impossible!I was allergic to the Pfizer Covid-19 Vaccines and Booster in 2021 so I have many side effects that I have/am dealing with. I also have Asthma and CLL. So, her health is much better than mine. Her main problem is she falls too often to live alone.
The ending came in October of this year. She fell 3 times in 2 days, calling EMS to transport her. She was getting her diabetic insulin out of the refrigerator and taking it without testing sugar. I’m the one in charge of meds but she was doing this at night. I would find her insulin in her bedroom after the fact. The last call for help, she was admitted for 3 weeks. I told my youngest sister that I could no longer take care of the older sister. My doctors were beginning to get concerned with my health and my Primary Doctor told me that he did not approve of me being a caregiver. He said I was the one who needed someone helping me.
Now, my older sister is in a nursing home, arranged by the younger one. Neither are speaking to me! They rarely answer a text, if they answer it’s with one or two words.
I invited both to meet me for lunch last week for the youngest sister’s birthday. I had a nice gift, like always and paid for the meals. Birthday tradition! Worst birthday luncheon I’ve ever experienced!
My heart is broken!
When our Mother died, everyone nominated me to be the Family Manager…an impossible position to fulfill! Mother’s last words to me were “Please keep the family together.” That is another impossible task!
My Mother died in my home while my husband and I held her hands and I held her close while my husband was praying. One month later my husband was diagnosed with Multiple Myeloma and I was his full time Caregiver for the next 4 years.
I’m not patting myself on the back and certainly not asking for sympathy from anyone. I’m just hurting inside!
I’m sitting at my breakfast table at 11:31 AM, it’s still 44 degrees outside and I’m still in my PJ’s. I’ve been up since 5:30 when my son left for work. I’m usually dressed by 7:00, with makeup and the works. I haven’t slept in 2 nights because of the pain in my legs (muscle disease from Pfizer) and because I miss the phone calls, text, and visits with my sisters.
I just feel lost in a world that I’m usually very active in. How do I manage these long winter days without my sisters. But I’m tired of being taken advantage!
