bipolar elderly

How to deal with elderly parents?
My parents always fight for no reason, tried to fix things. When I try to explain to my Mom says I'm like my dad and thats why I am defending him and my father does the same. My father is 65 and was recently fired by something he never did and any retirement package. She feels that all the years he worked were useless. He suffers from diabetes, hypertension and Cholestrol and refuses to take medication. I have to force him to take and the problem is I'm not always around. when my parents fight to stop cooking and eating it depends on the chips, sweet and types of food not to eat. He believes that drugs are useless and should be used as little as possible. I got pills made of herbs, but still undecided. I think that if we do something quickly, you are in a very bad. I love my father very much, but I cannot help it cuz i always have bipolar disorder. I know that a question of its length, but I would like some help. Thank you.
For starters, get rid of all foods not to eat first … out healthy foods there … I took my dad to a blood analyst, as it seems "more natural" and verifies the condition, and gave him herbs and … maybe this helps his father to take more seriously their problems … For some conditions, there are serious side effects, if the patient stops taking the medication abruptly, after the body is used to it (a known, died just because of that). Your parents have to find something to get busy with, so that his life will be more meaningful …. something we hope …. You can ask this question separately … Good luck
