Long term disability denied twice - is it worth getting a lawyer?

I have a chronic condition that's made it impossible to work my old job. Applied for LTD through my employer's policy.

First denial: "Insufficient documentation" - sent more docs
Second denial: "Does not meet definition of disability under policy"

I've been out of work for 6 months now. Living off savings which are almost gone.

Is it worth hiring a disability attorney at this point? I've heard they work on contingency but I dont know if my case is strong enough. Anyone been through this process?
