Feeling hopeless, should I still continue animation.

I really want to work for animation and even got a degree in computer animation, but I've been out of school for 4+ years and despite working on my artistic skills and networking, I can't seem to get my foot in the door. I've had this heavy case of art block that my portfolio is severely old work. I'd like to believe I've improved a lot since my school years but can't really find the motivation to update my work.

I'm not sure what to do, and feeling hopeless about the future and since the animation industry is having some issues. I fear that I got my degree for nothing. What can I do to change this mindset or should I just stop and pursue a different career?
