My sister partner has PMDD. We live together and it is awful. Her moods come crashing down before period time, she loses sight of herself, self loathes, cries all day everyday, can’t do her work, doesn’t eat, sleeps all the time, becomes completely irrational, has panic attacks, can think, can’t make decisions, doesn’t want to be around me, but must most of all, she wants to make such huge life decisions like changing jobs or moving out, thinking she would be better off living back with her parents in another city. When the PMDD subsides she says she can’t believe she even thinks of those things as it’s not what she wants. It is completely debilitating. I feel as though I am now a care giver, I get the brunt of her emotions, I have to get her out for a walk, to eat, to wash etc. I have lost 6lbs in a week through stress. She is on setraline and vitamin B from the doctors but this time, it hasn’t gone away when her period arrived. People tell me not to take it to heart but when she is distant, doesn’t want me near her, or to talk to her etc but it is very hard not to take it to heart. Please, is there anything else we can try for this PMDD? It is going to ruin our relationship
