Can of worms symptoms and conditions

Damn reading up on all these side effects shared here is really scaring.
Well I must admit that I certainly can relate to quite a few of them.
Well I took Yasmin for over a year,and my initial experience (say 6 months) was ok.
During that times my skin became flawless,to clear&radiant the best I'd ever had.
However beyond the 6 months things changed and I developed mad constant thrush
Really it was horrid,was put on fluconazole countless times,and I had never been one prone to thrush.
Furthermore every month during my period I'd get this mad headache coupled with dizziness and serious fatigue.
I was even convinced that I was anemic,because I'd actually go pale!Due to these headaches I decided to stop the Yasmin as I
Felt that really my life was at stake.In fact it was so bad I couldn't complete the that months pack.
Discontinuing Yasmin,opened yet another can of worms,perhaps due to me stopping suddenly.I developed severe acne,I was never one skin issues.
Well perhaps it could be attributed to the abrupt discontinuation of the pill.Sadly even 6 months of being off the pill my skin has not gotten any better.
As a result I have stupidly found myself having no choice but to go back to Yasmin.I have been taking it for just over a week,my skin has improved profoundly but I'm scared.
Moreso after reading everybody else comments,I'm really scared.If I'm to discontinue would yoi advice that I complete the cycle and not not stop suddenly?
Right now I'm ok just have slight nausea and occasional dull aching head.
Please can somebody give me advice.

I noticed a lot of postings about weight gain on Singulair, which is nowhere listed by Merck as a possible side effect. My 15 y.o. daughter experienced sudden weight gain at the age of 9 when she was actually underweight (BMI went from 17 to 21). To make a long story short, after being off Singulair for over a year, she is now over-weight, and diet/exercise have never made a big difference (gymnastics, swim team, figure skating, trampoline, etc.) Extensive labwork is always normal & there is no family history of obesity. It's a shame the quality of life of a child is RUINED by a drug that is deemed to have "no side effects", and the many drs. & specialists out there take it very lightly. We continually worry about our daughter's self-esteem, risk of diabetes, and other complications from weight gain which is not hereditary and goes on unexplained by the drug co. Reversing this weight gain has been nearly impossible. Everytime I hear a news report about our children being overweight and obese, it makes me angry because I think about the many kids that are taking this highly prescribed drug (for even the mildest allergy or asthma) and who knows how many parents don't make the connection!
