Good for you coming through your hard time and even wanting to get back into cycling. I know you can!

The only way I keep riding is because it's part of my routine. If I varied my activity too much, I wouldn't be able to keep it up. I know it's hard, but you probably already know that it takes about 6 weeks to establish something as a habit. If you can routinely work cycling into your life for the next 6 weeks -- even when you don't feel like it, and even if it's only a little bit, as the ladies mentioned above -- after that it'll start feeling more natural.
