Sometimes you can only hold on to faith (God, yourself, someone, something, etc). I hold on to my faith that one day my son would be 100% well and healthy. Of course, I'm not going to wait for a miracle. I'll try all possibilities and hope that one of them is the correct one. I'll just let God guide me 'cause sometimes my cross is too heavy.
My son is non-verbal and needs an augmentative and alternative communication (AAC; http://www.asha.org/public/speech/disorders/AAC.htm) device, which can cost around $5000 (what a ridiculous and offensive price). As an alternative, I bought TapToTalk (http://www.taptotalk.com/) and a Gameboy (http://www.nintendo.com/ds/systems/dsixl) for my son to use as an AAC device for about $300. Sometimes money is the least of my concerns specially when it comes to my son's health, but I don't have $5000 (cash or credit) right now to pay for a "real" ACC device.
In all, this is practically an experiment. I don't know how this will turn out and I might write more later.
