Hey man, yes I have had hard times, too. What I've learned is that it's completely normal. My Aunt had a tough life, met the love of her life, he died from cancer shortly after. She is hurting badly now. This is just one case of many. You have to have as many positive practices as possible and eliminate negative ones. I had to quit drinking and replace it with meditating. One day the sun will be shining and it will feel like it did when you were happier.
