skipy, Even those of us who can sing can also learn from listening to our own voice on a recording.One thing I have learned is, I tend to sing too fast.
Since cancer took my voice away I am unable to sing at all, and nothing is going to give it back. You can not imagine the depression that has caused. At least for you, there is a chance. All you need is some professional help. I say if you can walk you can sing.
