hi
you are not wasting the company's money if you go to a life coach. don't be scared to learn new coping and organizational strategies you can actually use when you are depressed to be more productive. your boss she cares about your productivity. it is good your company is willing to invest in you instead of dumping you. it is good that you are being groomed for a better position.
try to be optimistic about this instead of self-conscious. yeah, i know, easier said than done. and i have no business telling you what to believe.
But i believe a pro-active approach addressing the symptoms cannot be underestimated in value until you try it.
I use an organizational method called GTD or getting things done. there's loads of inexpensive software out there to support it. feel free to private message me about it if you want to.
