I would see a mental health professional

My lowest point was when my 52 year old brother died from a heart attack. I was in so much shock that I couldn't remember parts of the funeral. I had a constant headache the whole week which I got meds for from my md. After that week, the depression came. I was already on meds and seeing a psychiatrist but all I did was stay in bed for months. I lost my will to live. At that time, I was married. I was afraid I'd lose my husband, but he was previously married to a woman who was bipolar and had a lot of experience with her and her not taking her meds. That made me feel better knowing that he wouldn't leave me because I was so depressed and could practically function. This lasted a whole year after my brother's death. After that it lifted to where I was on meds for maintenance which I'm still on to this day.

Best to see professionals Dont self diagnose or listen friends or family
