I have felt this way, it's absolutely horrible, and scary, but I promise with medication, and then when you feel that tiny bit better from the medication in a couple of weeks, you can start doing little bits to uplift yourself further, like:
Watch your favourite movie
Have dinner at a restaurant you like
Have a facial or a massage
Get your nails done
Have a long bath with salts and candles
Listen to your favourite music
Eat a batch of raw cookie dough
Walk on the beach
Eat your favourite take away While watching your favourite DVD
Read an awesome book
When you are ready, it might help to make a list like this, of things you used to enjoy before you got so down. When you are really down even things you normally enjoy don't seem like fun, that's normal for depression, but once the meds kick in you will have that tiny bit of strength and you will start to enjoy things again, so if you plan to do them by writing it in a diary or calendar so you can get a babysitter or your partner to help out for an hour or two while you take some much needed "me time".
