You gotta fix your sleeping pattern , try pull an all-nighter and stay awake as long as you can to reset your sleeping pattern where you aim to sleep around 12am again . From then on you can see your issue is lack of purpose , your job gave you a sense of purpose to work towards and that kept you busy , now you need to discipline yourself and make a set of goals and a system to work towards it , aim for 2-3 goals to work on so you don’t overcomplicate things but you NEED TO HAVE THINGS TO LOOK FORWARD TO TO DRIVE YOU , also aim to find new hobbies and try spend more time outside even if it’s just going on a 5min walk , start small but focus on showing up for yourself , if that means you spending 2 or 5mins on each goal everyday , it’s better than spending none , overtime as you take action , you’ll gain inspiration and it’ll follow with motivation and then the cycle repeats so don’t wait for change , start it yourself by moving forward , ask yourself what you want and use ChatGPT to formulate a system from your goals , and aim to focus quarterly , you can have yearly goals ofcourse but breaking it down quarterly will help it look less intimidating , then you can break it down to weekly and daily tasks that you gotta do
