I can't

Me and my wife of 30 year's has never been apart for more than 3 days... It's now been 6 weeks. I lost her because 3 young thugs decided to hold us at gunpoint, robbed us, hit me knocked me out and shot her in the back... She is the kindest, sweetest most loving wife, mother, sister the world has ever seen. I've never know life without her. I have no memories without her in them. My head is still numb from the injuries. Can't think, eat, no sleep. Everybody says"you have to be strong", I can't I lost my strength. I'm told"you need to try to stay grounded". She was my rock, my strength, the reason for wisdom, my love, my heart, my everything and every reason to live. I love our kids. They will be ok. I can't make any sense out of this...
