Living with Oxygen: Is There Hope for Me?

hey everyone I'm curious about a few things.. I am currently on oxygen and have been for about six months now.. was originally put on it because my saturation of oxygen in my blood was incredibly low.. and because I have COPD, asthma, and emphysema is there Hope for me to eventually get off the oxygen machine or will I be on it for the rest of my life... because honestly I am depressed and deprived of doing so much I really want to be doing.. it often hase in tears because I feel like I am a burden to my family.. as I pretty much have to ask them to do everything for me... does anyone know what I am going through..
