Welcome aboard sir. Your story sounds a lot like a lot of ours, except you are a lot smarter/younger than a lot of us.
For many of us, nicotine was the root of a lot of health problems. Once you start focusing on yourself instead of getting a fix of something that doesn't even give you a slight buzz anymore, it is amazing how healthy and refreshed you feel. Quitting will change your whole life. Sounds lame, but it really will. If you need a contact or any help at all, don't hesitate to reach out. There is no better gift that you could give yourself or your family than what you are doing.
