You should eat more blueberries
I know people mean well, but seriously...
If you know someone that is seriously ill, one of the worst things you can do is suggest books such as "You Can Heal Your Life" by Louise Hay which ultimately just blame the patient for their problems OR tell them to eat more blueberries.
I don't care if you think I should eat more blueberries. All that tells me is that you are ignorant, and need to read something else other than Chatelaine magazine.
Go eat more blueberries yourself. And while your at it, think more positive, do yoga, go for reiki treatments, spend $300 a month on supplements, get psychotherapy because obviously you don't love yourself, have more sex, carry crystals, don't drink from plastic, go to a clinic in Mexico, eat only organic or macrobiotic, start eating meat again, never have a drop of alcohol, meditate religiously, work out religiously, and think loving thoughts about everybody every second of every day. If you don't do everything I have suggested, then you obviously don't want to truly get better. And if you do do all these things and you still don't get better, it is because you didn't try hard enough or want it to work badly enough or you just plain didn't do it right.
After all, it is your fault.
