Can you break it down into very tiny chunks? 50-60 hr is no small thing. Can you just set a timer for 15 minutes? Starting can be the hardest thing. Sometimes I just need to prep the task, just pull together what I need, then take a break. Make your work space inviting. Light a candle and/or listen to something pleasant (music, a podcast). Omit other distractions. I installed a site blocker on my computer so I can't lurk at specific sites for periods of time. Plan a reward for yourself after your first tiny goal is met. You can absolutely do this. You're going to feel so much better once you begin.
