I'm more into expressive dance.
I'm really sorry to hear that your Dad passed away, the same thing happened to a close friend of mine just recently, and it was just horrible.
I think talking to someone would definitely help, friends can really help you through tough times. If you don't have many in real life, you could always resort to the internet as you'll find a number of kindred spirits, probably equally depressed. There are a number of forums on the internet specifically about depression, so just give those a google.
(For particular issues you want help with - try Help & Support.)
Or KHI's fanclub section where I think people have the opposite problem; I think the 'friendliest' people on the site reside there.
And of course you're always welcome to PM me if you're feeling really low.
Feel better soon.
