I'm about to reach 30's

I'm not sure what is happening to me..
I'm not so happy right now.. But I couldn't figure it out why
I'm trying so hard to be fine forget about those left me..
I wanna be better but when I thought I'm on the right track suddenly I feel like I am not in right place..
I'm about to be in 30's but I haven't achieved so much.. I wish I could be just like a normal person..
I've tried so hard I wanna give up..
Again.. I wish I could turn back time...
I'm still looking my purpose and why am I here..
