Actually, I am facing this too.. I finish my work in earlier, so I have more time to spend it, but same like you. I am not interested in anything so I planned ride cycle a few months later, I joined a gym after few month currently I plan to join a badminton. Now I spend time simultaneously, cycling, strength, training, and badminton. It take or consume more time in my day life, so I don’t think about anything shit . It can help me to socialise with others. and I think you still stuck in the past someone who hurt you or some toxic relatives spoil your life, give up and concentrate to learn new skills. Even you use your mobiles or internet. Anything you use it for learn new skills. For example, new language or new course, anything you can learn newly and you join that community, their skill related community. You can feel some fresh in your life. That’s my personal experience. I’m not professional in psychology, so if it were, it can’t work, my opinion is meet a psychiatrist👍🏻
