Every time...

Every time I get super depressed my fiance gets angry cuz I don't talk much. I don't even know what triggers it or anything since I only found out about my depression like a month ago. I have major depression, I don't know how long i had it but its been at least 3 years. I only renctly been having dark/bad days at least once a week. My fiance always assume he did something when it happens and gets mad I don't talk to him about it. Honestly I just can't cuz I loss my voice and no idea what is happening since these dark days are new. Right now I'm kinda bad but not that bad as if I was wont be able to type this. I tell him its not this fault when I'm feeling a bit better but it don't stick in his head. But he still assumes and its hard cuz then a snap at him then I don't want to be near him but at the same time I don't want to be alone.
