It's not too late. I went through ROTC with a 26 year old cadet, who got screwed over by the Captain and new incoming Commander. She was supposed to commission this Spring, but the bureaucratic corruption in our detachment is ridiculous. She's graduating this Spring with her nursing degree and going to apply for Officer Training School after her tour in the fall.
Don't compare yourself to other people. You have a different path. You'll be alright.
