Today is my bday turned 29 but how can I fix my life step by step ?

I don't know why but I always felt so lost in life since age 22, can't believe today I turned 29 and I don't even feel like oh look it's my birthday. Like my brain doesn't click the fact I'm another digit older. I'm feeling so overwhelmed and internally unhappy and unfulfilled because I have no acheive to overcome my goals and fears all this years of living. I still wish in my head that gosh I wish I can become 22 and work on finishing college. Work on getting my driver license. Work on getting a job. But for the last 6 years I've been homebody not doing anything but living in shame fear and anxiety.
