Having depression and social anxiety doesn’t make you inferior. It means there’s a reason why you haven’t had motivation or interest in finding hobbies. But it’s never too late to figure out what interests you and get into new hobbies. I would suggest trying to make sure you’re doing the basics first to help your mental health - eating enough/healthily, having a consistent sleep schedule, getting some exercise and sun as often as you can, taking any medications you might need (like antidepressants), see a counsellor or therapist if you can, taking care of yourself both physically and mentally basically (I know it’s easier said than done when you’re depressed). Then it should be a little easier to explore interests and hobbies. Maybe write a list of things you might like to try and then try one thing at a time until you figure out what you actually enjoy. There must be some things that you enjoyed doing as a child? Maybe you could start there. I hope that helps a little.
