I'm not entirely certain this is the right place for this question, but I can't think of anywhere better either, so here it goes.
I am currently suffering from moderate-severe depression and anxiety, likely related to bipolar disorder. I've just begun receiving treatment, thanks to obtaining health insurance from my employer. Unfortunately, it has caused me to miss a significant amount of work over the past several months, and continues to make it difficult to impossible to work a full 40 hour week. My employer has been very understanding through all of this, but I'm still paid on an hourly wage, and all of this missed time has resulted in a significant drop in income.
While I am hoping that my symptoms will improve with treatment, I think it would be foolish to assume I'll never miss work to them again, even after getting out of the rut I'm currently in. As such, I'm hoping to obtain disability insurance (something that is not included in my employer's insurance plan.) Unfortunately, I know almost nothing about insurance and have no idea where to even start.
How should I go about searching for disability insurance when I'm already dealing with lost income due to disability? Are there any plans or providers that will help me at all through my current situation? If not, is it even possible to find one that will cover me at all, or fairly?
Most importantly, what information do I need to know in order to find a good plan and make sure that I get a fair deal?
