Oh god yes, this is totally normal so please don't worry!! I have been through CIN 3 and LLETZ once before in 2008 and then again now. I'm just awaiting my second biopsy on Tues due to muddle between private and NHS and also possible CC being there too. Not nice having to go through a punch biopsy again. When I had LLETZ the first time I was at uni living away from my family and having my partner at the time sleep with someone else whilst I was recovering from the LLETZ. Now I have to go through it again it's brought all the emotions back. I'm not with my lovely husband to be and he's nothing but supportive, however I still live away from my parents so I always find that aspect hard. It's been an emotional time and working for the police, I'm finding my job has been making me teary when having to deal with not very nice things (that I usually wouldn't be bothered about).
LLETZ isn't nice and it can make you feel out of sorts and like Molly said, you'd had strangers mess about with you and you may feel invaded. Everyone deals with it differently and you are no expcetion. If you feel upset then that's normal, you've been through a lot. I know exactly how you feel and I just know it's starting all over again for me so that makes me scared :(
I hope you;re feeling a bit better, try and cheer yourself up by getting out and walking, taking your mind off things and enjoying some of this lovely crisp Autumn weather :)
