Stop the nonsense, take care of your parents...
Start by;
1. Making sure you know their blood pressure readings for the past 3 months, their blood surgar, HBa1C, their lipid profile, heart health for one year.
2. Make it a habit of calling them at least weekly to see if they're fine, are they still doing things they used to or became weak to do, eg. Going to o church, small gardening.
3. Do they have a doctor's appointment? Go with them.
4. Do they eat healthy? Adults eat cheaply for the cheapest food is the most healthy food and it's what they need.
5. Visit them once in a while unannounced.
6. If they have chronic diseases like diabetes, are they still taking the medication, is it still in stock or it's done... When are they seeing the doctor again.
Parents are like brothers and sisters, we don't get who we want but must love the ones we get and she/he's the one you got, so you just have to love the one you got...
