Why does everything have to be so hard?

I just want to be at a point in life where I can at least feel comfortable my life again before it all got taken away. Nothing is going right at all. Not coping with the death of my son, not knowing what to do for career, arguing with my OH all the time because we can't agree, family drifting away from me because I'm the odd one in the family who seems to be doing everything differently, they've all got living children and happy lives but I've got the opposite. This sucks, this really does. My anxiety & depression is getting worse every day, I just want to bring my baby back and make everything ok again. Happy f*****g new year to me! Maybe this is all I deserve in life 😔💔
