Where did you hear her meows? If she has a nest full of kittens, she won't be able to leave them to come to you, you'll have to go to her. But she'll be starving hungry by now, so tomorrow nip down the shop and buy a packet of Dreamies cat treats, they are virtually irresistible. Put some in your upturned hand and hold the rest of the packet in your other hand and shake it, whist calling to her, softly. Listen carefully and really hone in on her meows, you might have to get down on your hands and knees. Considering her hungriness though, could you put some of her favourite food (or plain tinned tuna) in a bowl right now and take it to where you heard her meows and leave it as near as possible? I know it's dark, getting late, and other animals will eat the food in a flash, but she might just be able to leave her nest long enough to eat something without endangering her kittens safety.
You also sound very depressed to me. You might need to see a doctor. I suffer depression. I see a doctor.
