Nothing has lapsed yes. I have 2 months to decide if i use COBRA or do my own thing. The problem is, i would be locked into a $600 a month insurance payment, $3000 deductible, and the 20% of the bill. Being unemployed (for the most part) and getting my own business off the ground, it's a big bill to handle.
You are never locked into COBRA - you only have a limited time to sign up for it (30-60 days from the qualifying event) but once you sign up, you only pay month to month and you only have coverage while you are paying it. You get a 30 day grace period to pay each month, but once you lapse the 30 days it is cancelled and you can't get it back.
If you are starting your own business - you need to think about your health insurance and start shopping around for other alternatives. In the mean time, you could get the COBRA (month to month) until you have another solution. Just remember - if you don't sign up on time, it's gone. The COBRA is also sometimes needed if any new policy has a pre-existing condition clause. Also look for catastrophic coverage policies - they cover major things, but you cover all the regular stuff.
I'm sorry you are in this position - I've been there before and had to decide if COBRA was a good choice or not, even with the higher price tag.
Here's another thread that dealt with COBRA issues.
