Sign Language resources

This is my first time using a text board but this seems the only appropriate place.

I decided to self-learn some sign language because why the fuck not but I'm finding it exceedingly difficult to find any decent resources around the internet.
Specifically I want to learn ASL, could you guys point me in the right direction? Videos, textbooks, whatever.

Also do you think this is a difficult language to self-learn since it's so...physically involved?

Any help would be appreciated, I'll check this daily
