Gosh, I am so sorry to hear this. I have noticed with my son who has severe depression that he doesn't want to do anything he normally likes as a symptom of his depression. When you say your depression is better, what are you basing that on? Sometimes my son is sad, apathetic and symptomatic from his depression and sometimes he is numb and feels nothing. Both result in his not wanting to do anything. Are you still working with a therapist? I also am now a believer in DBT therapy. My son and I do a one to two days a week of "opposite day". Part of DBT therapy approach. Opposite day is when you do the opposite of what you feel like. So, not wanting to game (if that is your thing you'd like to get back to)? Then on Opposite day, you have to do it. Whether you feel like it or not. If you are withdrawing from people, on Opposite day, you have to connect with either messages to someone, talking to them or getting together. We only do opposite day two times a week right now so it's not overwhelming. But it helps my son get back to it. When he does the things he's not really wanting to, he is feeling better. So, maybe you could try this too. https://www.mindfulnessmuse.com/dialectical-behavior-therapy/10-practical-examples-of-opposite-action-part-one
Perhaps you need a bigger diversity of interests so you can jump from one to another when you please. Can you try a sport or two, and helping others is rewarding.
Two possibilities. Your depression isn't gone at all, as this is a sign of depression. The second is that you're changing and are no longer in love with these things.
