WFH Guilt

I am an engineer working from home making $98k. I am so lazy with work recently. I will respond to people right away if they ask for urgent things but I have been working on other long term reports and I get so overwhelmed and accomplish NOTHING. I have tried telling my manager in our one on one meetings but he pretty much just tells me I’m doing a good job and no one has complained about my work. I feel so guilty that other people think I am actually doing work when I am not for most hours of the day. He himself usually just tries to get away with the bare minimum and so it’s trickling down to me. I get so distracted at work with my phone, falling asleep, etc but feel like I have lost all control of any structure during my work day. I feel so privileged to have this job but I just cannot get any more energy. Should I just find a job that requires me to be in person?
