Hey hun,
Please remember this: NOTHING is more important than your own wellbeing. Your mental, physical and emotional health and your real life are the things that matter above and beyond anything else.
I don't care if it takes you a decade to finish making this game, or if you trash it in 2 years and do something else. In the end YOU are all that truly matters, so please take all the time you need to take and do it the right way, please don't push yourself and don't listen to people who are getting upset over you doing whatever you choose to because at the end of the day you do not owe them anything.
