I was on those tablets as well (although they are called 'Cipramil' in Ireland, for some reason) and they worked pretty well, not having nearly as many side effects as Prozac did, in my case (Which gave me the shakes, continuously and made me a little bit manic!).
I don't think 10mg should cause you any major side effects, I was on 20mg and I was just 15 (and weighing around 6 stone) and nothing really adverse happened. I know everyone reacts differently to medication, so it is good that you have told people on here who know you, as they can look out for any changes in your mood or personality.
You may as well give the CBT a try if you have your name down for it and are getting it through the NHS. I had a little bit of it and it wasn't effective for me but I know for many people, it helps them to figure out where they're going and take control of their life a little more. Counselling of some kind would probably help you. Sometimes just saying your thoughts aloud, and working through them can be very therapeutic.
Anyway, good luck
! Give the medication a few days to a week to kick in, and I hope that it helps you.
