Am I too old?

Et

I graduated college at 23. Didnt know what I wanted to do so I worked for years and now I'm 28. I want to apply to nursing school but need to take all the science pre reqs since I have a bachelors in arts. I have my cna, so i figured i would work for a year then apply to nursing school. The program I'm looking at would be 4 years and I would end up with a DNP (doctor of nursing practice). By that time I will be 34. Does that seem old? I feel a little discouraged. I also dont have family in my life and they've never been supportive. So I dont feel like I'm good at anything. I have depression and anxiety so maybe it's just my own mind making me feel down.
