I have severe PMDD, once a month I want to check myself into a hospital and say I can’t cope, but I don’t because of my children (single mum) I suffer 7 days before my period and the first 3 days. I have been prescribed sertraline after the contraceptive pill didn’t help. Each month I am too scared to take it in case I feel worse. I am on the first day of my period and on the verge of wanting to give up on life, I won’t, but it’s all I can think of. I want to try the sertraline. Should I start today? Or at another time in my cycle? I’ve been prescribed it for every day of the month. How long does it take to help? Will I feel worse to begin with? I have no plans for October half term so thought tomorrow might be a good day to start? I have the week off work and no school runs.
