I'm sorry to say but I've stopped caring about my health
You can't mean that? What are you doing that is bad for your health?
I always think about quitting smoking, but when it comes to quitting for good I don't want to do it.
Being healthy is important but it is okay to sometimes do things that are not good for us. It gives us pleasure to go on and be okay with life.
Yeah, but it's not fun when I die early.
If your realize that you want to live a good long life, then I believe you should really try to stop smoking. While going off track is sometimes expected, why not still try to get into rehab to finally better yourself and get healthier?
