You FIL might be a bad example for yoga and meditation. Either he has too much negativity in him already so the outwards effects of the practices appear minimal or he is using a wrong approach. I got inspired with yoga when I attended the class of a senior Art of Living teacher called Kishen Varma. He was 70+ but looked just 50. His mental and physical fitness was just mind blowing. So don't label all these practices as useless just by looking at your FIL. The only way to judge these practices is to check how well they help you in building your faculty of awareness, so you can catch yourself reacting to situations as they are happening. The purpose of all these practices is to help you in being at peace with yourself. Whether you do these practices of some other practices like prayer or whatever then the same end goal is achieved.After getting into these practices my health has tremendously improved. I hardly fall sick. I have suffered for years from eczema and now I see my body healing by itself whenever I have a flare up. This is something I have never seen in my 32 years of life. A huge part of my insecurity is the fear of being abused when I am sick. But now that I am actively pursuing these practices and seeing the strong effect it has on my health, I feel it is a very good investment. My husband tried 3 endocrinologists and all of them told me that hyperthyroid has a huge impact on the mental health. I have also interacted with a lot of patients who have graves disease and they all talk about how it affects their mental health. When my husband was not on meds just after my delivery, he was very emotional. He would get angry or cry very easily. Once during a fight just a month after my delivery he started running around the whole house pulling his hair. I have never ever seen him behave like that. But I asked my husband many times about how the disease is affecting his psyche and how he never felt anything different when he was not on meds. He tells me that he just felt stressed by the lack of sleep but did not feel anything different. He is unable to explain his actions. This puzzles and scares me the most. So I keep wondering is it just thyroid or is there something to it. How can somebody have such minimal self awareness. For example when I was going into postpartum depression I realized something abnormal was happening to me and I told my husband a couple of times about it. I told him I think I am slipping into postpartum depression. My husband did not take it seriously. But my husband could not detect his thyroid issue. The blood test finally revealed the truth. Given my husband's nature these incidents just spook me. I have been married to him for 10 years. Before my delivery I knew him for five years and was totally unprepared for his bizarre behavior. Outwardly he is a very calm and friendly person. I have never heard him crib about work or anything. He is a very safe driver. Never uses swear words. He is overly cautious. So how does somebody suddenly do something so bizarre? Is he suppressing his true feelings all the time, is there an unknown dimension to him, is there a hidden condition or have I not understood him well enough. These questions keep popping in my mind. On one side I want to be a supportive spouse but on the other hand I just feel I am loosing the strength. I have a very good relationship with my SIL (touchwood). I confided a lot in her. The sad fact is that she knew more about my married life and showed much more care and concern then my brother. She would call me often to find out how I am doing and be as supportive as possible. What I cannot digest is how he was not more involved. Either he felt at peace that his wife was talking to me and I was being taken care of or he just did not care. I have taken counseling with three therapists and finally I came to the conclusion that counseling is not very helpful. Therapists do not offer much support. I guess I should just accept these gray moments and move on. Happy Ugadi and Ram Navami to you too !! Thanks for pitching in. Kavya.
