Health is a state of complete physical, mental and social well-being, and not
merely the absence of disease or infirmity. ~World Health Organization, 1948
Physical pain is nothing compared to state of mind. I have found, in my experience, that chronic pain can lead to a debilitated state of mind. So, no, I do not find it selfish to concentrate so much on my physical comfort, in this situation. There are those who do not understand. My son says that they are just stupid people, and I shouldn't worry so much about what stupid people think. That is probably very good advice. I am learning to state that this is what I need. In the past, I have always tried to mold myself into what is needed of me, and to conform to what others expected of me. Sure, some people won't get it. But, that has to be alright.
My situation may be unique to me. But, you have your own situations. Ask yourself, what is it that you are trying to mold yourself to? Are you trying to mold to others' expectations? Or, are you letting your experience with God dictate how you mold your life? You can only function within God's Word. You are, after all, a Christian... not a worldly man or woman, as some people like to be known. It is reasonable to assume that you won't fit-in to what many people will think you need to be. You can't let that hinder your growth in the direction that God would take you.
Not much in my life has been done by accident. On a more personal note, even my children were not conceived my accident. We decided to have a baby both times, and both times we became pregnant within a month and a half of making the decision. My children were wanted and asked of God. I wanted them then. I am glad I have them now. I would never have wanted to say to my child, "You are a mistake." God doesn't make mistakes. I planned my first child for 20 years. But, I waited until I was married before beginning. Some things are worth the wait.
I did not choose to have these health problems. Rather they came to me when I was doing everything in my power to take care of myself. I was eating right, and exercising regularly. I was taking my vitamins and herbs as well. I have never smoked. I have had very little to drink in my life. I have never done recreational drugs. I avoided cholesterol. I was drinking tofu smoothies and protein shakes and running 5K's and riding in roadbike rides around the state. I was actively pursuing good health. I also took care of my mental and spiritual wellbeing, though I didn't pursue those things. They have always been a part of me. I feel as if I was born aware of God and being sought by Him. My life has revolved around my soul most of the time, though I have lost my focus and wandered a few times. If you see me headed in the wrong direction, God is behind me.He is where I am coming from. If I am going the right direction it is because He is carrying me as I have sat in his lap for most of my life.
Learning is something that has likewise, always been a part of me. I have been accused of being born reading. I don't remember learning to read. My Mom taught me the alphabet before I started kindergarden at four years old, and from there the letters began to dance and they began their magical choreography of words. I have actively taken classes of one nature or another for my whole life, until the last two years. I was 44 when the accident happened, and I had been learning for 44 years. But, physical health was something I had to work to obtain.
I don't know what will happen in the future with my health. I have no way of knowing when or if these problems will be lifted off of me. I can know how I will respond to these circumstances. That is all any of us can know. In my situation I choose to actively set parameters and make decisions that will move me in the direction that I want to be five years from now.
Your situation is really no different. Maybe in particulars, but you have to actively make a decision where it is you are headed. Take charge of your direction. Be what God wants you to be. Serve Him in a manner that you choose. That is your gift to God. Don't let it be accidental...something that just happened. Choose your gift prayerfully and give it to God. No musician learns to play accidentally. They don't just wake up and say, "Wow, I can play the piano, so I guess I will play for God!" No, they actively pursued learning the piano at some point in their lives. Go ahead, make your choice and run with it!
