Jeezus man, reading this made me feel for you; troublesome times indeed and having gone through various parental complications like yours myself I empathize.
It seems like every way you turn there's a hit, I know that feeling too, and it's terribly draining on...well, everything. (Except your hair which is magnificent.)
Keep your head up (if you can under the weight of your hair) and keep pushing forward, or at least remain standing, and things will start to move in the right direction I'm sure.
You know where I am if you want to unload a little.
