How do I slowly stop using my straighteners?

Asked: How do I slowly stop using my straighteners?

I really want to grow out my hair so its long(it's about 3inches past my shoulder now) and I have proper bad split ends. I am going to get the split ends cut off so I can grow out healthy hair.

but…

I use straighteners almost every day. I know its proper bad which is why I am trying to stop. It's kind of like an addiction, I feel really insecure with my natural hair (which is these horrible,flat waves just at the bottom). How can I slowly get my self to stop using straighteners, because I wont be able to just suddenly stop using them all of a sudden, it would be too hard because of my insecurity.

Also,if you have any tips for growing out hair/keeping hair healthy&silky smooth,please let me know.

Thank you in advance x
