Sorry to hear things are not going well, and very sad to hear about your cat. Pets are so special and it's not fair they don't get to stay around forever, I know that feel. At least you can think you gave your cat a good home for its entire life and that's very important :)

It's also important to maintain a good balance between work and life, and your "work" here is game development. Start small, like go for a walk each morning and evening, you could consider that your "commute" so you start working on games after your morning walk and you stop working after your evening work. Take a break in the evening and do something you enjoy, whether that's seeing friends or playing games or just lying on the couch watching shows.

Try and work a little exercise (cardio or weights or whatever you prefer, it doesn't matter) and meditation into your routine, they will help your brain produce better chemicals which will keep your mood more steady and at least help a bit with depression.

I hope that helps. But overall, do look after yourself. Your personal health is more important than video games or random people on the internet like us.

Do what you gotta do to take care of yourself. I have an 18 year old meow myself, and I'd probably have to take several days off work to deal with the pain when he eventually passes. We aren't going anywhere. Seriously, take care of yourself; we look forward to Zordak whenever it's ready. 

I'm going through the exact same thing since I writing a novel and even though I'm almost done, life, mood, and this 'blaming yourself for non being productive while doing nothing' circle is real. Thing is when I'm out, this is the only thing I think of, I'm like 'damn, I want to write, right now' but when I'm home, I'm more often on 9gag or playing a game than writing. Just for you to know that you're not alone in this, and sometimes, those creativity emptiness can be somehow productive, because the moment you create again, you do it with a fresh eye and a big rage.

good luck man, keep it up

your game will be great.

Sorry to hear about your depression and hope you are doing well. Zordak is shaping up to be an excellent game and it's clear that a lot of work and passion has gone into it. The pixel art animation is fantastic and it feels like a perfect homage to the Metroid games. Really glad that you're continuing to work on it.

There's no shame in taking time out if a project it getting you down though. Video game design is an artform and if you're not feeling it, then it's hard to force yourself to do it. Sometimes it's good to take a break, play some games just for fun or even do a small game jam game as a palate cleanser. 

Best wishes and keep up the great work (but don't feel obliged to work!) :)
