So I just wondered if this was normal...when I am due in my period i can feel so low...almost suicidal...crying most of the day off and on and just like a thick black cloud which I cannot snap out of...I get severely anxious and quite paranoid and just very negative thoughts....my memory gets affected and I could sleep for hours and hours is this extreme? Normal? I also feel very insecure during the time...this tends to go on even when my period arrives...
