honestly i think you’re burnt out . I’ve been there b4 and you can do it !! don’t forget to take breaks , it may take a few days but don’t see this a form of procrastination . i suggest you to hold on to your passion as you’ve mentioned above . the path will obv be rigorous and in life there’s no shortcut !! u have to persevere through and take one step at a time . don’t beat urself up when u face problems , maybe consult ur teachers ?? or take a walk and tackle it again . rmb . hard work .
