OP, keep going and as many have already said, keep talking.
Can you rearrange your day off? It’s important to spend time doing things that you enjoy.
I have been affected by depression and I’m getting better at spotting the early signs and acting to stop the rot from setting in. Go and speak to your GP, it was the best thing I did. Also don’t be afraid to take a step back from responsibility inorder to recharge and get yourself ready to take on the world again.
