So many emotions

Ill try to keep this simple and short. So 6 months ago my dad committed suicide and my mom tried to follow but luckily i stopped her. Then 4 months later i found out i was pregnant. I was over the moon. July 4th i had a miscarriage and my heart shattered. We're ttc again but im so beyone depressed. My mom has turned back into a raging alcoholic and wants to kill herself. Every day im worried and just drained. And last night i was telling my husband how ive been feeling and his response was "why do you keep dwelling on that crap" umm excuse me??? How many fucking deaths need to occur before my feelings are valid?!?! Im just so tired and sad and depressed and DRAINED to my very core. I dont even know where to begin to pick up the pieces of my life. The thought of getting pregnant again seems to be the only thing keeping me alive and going...
