Lisa, please note the first week or so things can get worse on the pill whilst your body is getting used to the additional hormones - it was my hardest time. After about 8 days things calmed immensely though so just be prepared in case you give in too soon with it.
Also, every pill makes me feel completely different so lots of options if this one doesn't suit. I found (and everyone is different):
Microgynon (Levonorgestrel & Oestrogen high) - very relaxed but no motivation which I could see moving into depression over time, acne which never had before.
Logynon (Triphasic of Levonorgestrel) - when oestrogen was 40, too over stimulated, the rest similar to Microgynon.
Loestrin (Norethisterone high, oestrogen low) - very relaxed, sleep very long, motivation low, a little moody.
Brevinor/Ovysmen (Norethisterone low, oestrogen high) - more motivated, less sleepy, breasts more tender, too stimulated/anxious at ovulation time (pill doesn't stop mine) but I switch to Loestrin for few days if this happens.
Norimin (Norethisterone & oestrogen high) - motivated, a little too moody, hungry all the time!
All 3rd gen pills like Cilest, Mercilon, Marvelon, Qlaira made me feel like I'd had a labotomy! However, many women prefer the newer ones so this is more to demonstrate the differences we can experience.
Also, if ovulation doesn't occur then you will still feel your own oestrogen surges but the pill dampens things massively as I could barely leave my bed before I went on them (mainly severe nausea and anxiety but completely understand the suicidal feelings as you can't imagine feeling normal again and the adrenaline rushes are terrifying).
