Premium up over $2500 per year

I just received notice from my insurance company that I have a grandfathered in plan so my current insurance as is complies with the new law but my premiunm is going up $215.00 per month or $2580.00 per year. I thought this was supposed to be the affordable care act. My plan is not a fancy cadilac plan but catastophic insurance. I have a $5000.00 deductable so I normally will not even get close to that yearly. I am shocked and angry and may just drop it and take the fine/fee/tax of $95.00 per year saving myself over $2400.00 per year until I qualify for medicare in 4 years. If I get sick or injured I can apply and not be turned down right?
