I use a canary pad next to my mouse pad to help me stay focused. When the page is blank, I write down the next three things I need to do. As I am coding I add more things to the list. Not highly detailed, for example, "user profile page". Unless more detail is helpful. The point is the canary pad needs to be a tool to help focus, and not become the focus. When I get distracted, start staring, or get lost, I look at the pad. Don't use any software as a substitute, it needs to be pencil (or pen if you prefer) and paper. The kinesthetic feedback of writing is part of what helps learning and helps you stay focused. And here's the best part, I gamify the list by crossing out the completed task with a red pencil. It's so satisfying. And gives a strong visual account of my productivity. Ticking a checkbox doesn't remotely compare. When the page is full, rewrite the incomplete tasks on a fresh page and begin again. I know it sounds laborious but the rewriting connects you with what needs to be done. I usually rewrite once or twice a week. It sounds to me like you get into a rush mode and get sloppy by forgetting to test the corner cases. The pad will help. Since you mention feeling depressed, I'm also going to put this out there. It may or may not apply to you, and if it doesn't apply just skip right on past this. Does the use of alcohol or other drugs correlate with the intensity of your feelings of depression? I mention this because alcohol and a lot of drugs are depressants. Depression can also be anger that is focused inwardly. In that case, find a way to express that anger externally. It may be messy at first, but the point is to get anger flowing in the opposite direction. From there you can refine how you express that anger externally. My journey with my anger-centric depression started with smashing things and then evolved into establishing healthy boundaries with the motherfuckers who were pissing me off, and also recognizing when I need to take responsibility for myself, my work, or my behavior. And of course another cause of depression could be Neurochemical imbalance. I'd look at possible substance abuse issues and anger before seeing a shrink for antidepressants. And take some time to enjoy your beautiful family.
