Would it be a waste of money to get braces? I have crowding, an overbite, and a chip in my front tooth (Photo)

I'm almost 19. When I was younger I sucked my thumb and now have an overbite. I have crowding on the bottom and on the top also they slightly cross in the back. I am wondering if it would be a waste of money to get braces. Also how long would i need them? (when I went to the orthodontist with my sister they told me about a year and a half). Also.. I chipped my front tooth, which I haven't went to the dentist for. I'm self conscious of them and I would get traditional braces if I got them.
