Strawberry, I don't know if people giving you advice is gonna help. You post about this a lot, and if you want to enjoy writing again, you ultimately need to find some internal motivation. But for several years, I also was uninspired and couldn't finish anything despite having a history of finishing stories, and I only recently got over it when I started working on a script for a project I've been planning for a long time. For me, I think a big part of my problem was expecting perfection out of myself and not being able to disable my critical filter long enough to write a rough draft. So I guess ask yourself if there's a reason you aren't enjoying it anymore.
Also, having a project I'd been planning for a long time is also proving to be quite helpful. This is the third time I've tried to draft this story and the first time where I actually felt like I had it right. It took a while before the characters and situations started to seem really real to me, so maybe you just need to commit to a single project for longer even if it doesn't immediately grip you.
But really, if you want to be a writer, surround yourself with other writers. Not people who say they're writers, but people who actually write and finish projects. The people you interact with most with have a huge impact on your behavior, productivity, etc., in general, so you want to spend time around people you want to emulate and see if you can pick up some of their habits. Maybe you should join a critique group or something.
