premenstrual syndrome

hi there,

I came off the contraceptive pill about three months ago and since then have noticed that the week before my peoid and the first few day I have really bad feelings of low self esteem and worthlessnes. I cry at the drop of a hat and simply feel rubbish about myself. Its getting to point where it is interfering with my work and causing problems with my relationship. My poor boyfriend does not know how to make me feel better and I just fall apart on him once a month. Can I do anything to reduce the low feelings I have and help keep me feeling happier when I am due on. We want to start a family in the next 12 months and I worry that my low feelings will get the better of me.
