Is nirvana really worth it?

I know some people may be raising their eyebrows at this, but this is for all the Buddhists. You spend your whole life doing good, stripping yourself of wants, basically cutting yourself off from the rest of the world to pursue happiness, and then you hit nirvana and your dissolved. Thats it. no more consciousness, no more nothing. Given the choice, would you rather live a thousand lives in pain or none at all? is it better to live life suffering rather to not have lived at all? and then your just gonna disappear, after spending all that time and devotion and disciplining yourself, your "reward" is non exsistence. Is life really that bad to not want to exsist anymore? I mean I come from a comfortible life and im sure that plays a role in my outlook, but even if i was suffering, would I really want myself to stop exsisting and just merge with nature?
