Hi Knotty
I 100% can relate to what your saying, I was so convinced that I had lost the plot that I actually researched it on Google. Was the worst feeling I ever had, terrified me. I, like you was originally on patches but changed to femiston 1/10 then went really downhill quickly. Felt completely not in control.at all and scared me so much. I found this forum and asked via a post if changing can have this effect. I was well supported on here.and someone suggested the femiston was not the same strength as the patches, thus leading to dip in mood and MH. I went back to nurse at GP surgery and she checked and agreed. She also suggested changing to gel and tabs (tablets for 12 days only each month. Gel daily).
5 weeks into new gel and tabs regime and I feel so much better, almost normal - as normal as any woman in peri can feel. Talk to your doc as from my little bit of experience I realise that hrt is trial and error and you may have to try a few to find what suits you ,. Your not alone, your not losing the plot, really really felt the way you do. You will come through and while your searching for normality again please don't be shy to offload and share via here xxx
