I'm 46 and since last Monday literally I've felt tearful, very low mood, decided I hate my job and want to pack it in (which affects everyone in the household not just me as it's a family business that I'm in charge of). I'm finding what used to be simple tasks quite overwhelming and if I can't do it straight away I'm screaming and crying over it. I'm an emotional wreck.. I feel like my whole world has turned upside down and yet there's no reason for it. Last night i was so angry I slashed my arm with a razor and really wanted to leave the house and do worse. Instead I sobbed in bed for hours. I'm just not me anymore and I don't know what the fuck is happening.
