Happens to us all man, seems like your perseverance and family love saw you through it :)
When i get down, i know i have to shake it fast or things just won't keep moving forwards. Similar manner, I've sacrificed certain 'conveniences' to create something lasting ... at times, it can be really tough to keep going with it all, knowing however only your own will can make it come through. When down ... best to get it out the system asap! :)
