Hard to cope

Hi..I just lost my amazing Father 3 weeks ago.  He was a healthy, fit, active man who after having seizures in his arm had an MRI.  5 tumors were found on his brain.  That was Aug 28, he passed 6 weeks later.  My sister and I cared for him and watched him suffer, it was the most horrific thing i have ever gone through.  My poor Dad, lost use of arms, legs, slowly his mind due to the tumors.  It was numbing to watch and try to help him cope.  I cannot even explain how unbearable it was.  He was my world, so very close to him.  He was the most amazing person, funeral church was packed, standing room only...loved by so many. 

I lost my Mom just a year prior to this, so now i have no parents.  Surreal.

I just do not know where to turn.  Have amazing family support but i just want to lock myself up in my house and never come out.  Reaching out to others who have lost a Father or parent would be very helpful to me.  I know i am not the only one going through a devestating loss.  God bless.
