I Just recently broke the suspension right on the frame and where it is welded i am new to Chevy/GMC this is my first GM truck but I need help or ideas on were i can get replacement parts to weld on to it or if it can be repair welded PLease help...

 

It looks like who ever did the original lift modified the bracket to make it fit around the existing bracket for the cab??. If this is the case the structural integrity was compromised. Take it to a Frame Specialty Shop and have a new bracket welded in place and additional support added due to the stress caused by the lift. Don't forget to due the other side because it is most likely going to break also.
Lift Kits and larger tires cause additional stress to our trucks and if you cut corners things will break and break frequently.
Good Luck

Any kind of welding or fabrication shop should be able to help you out. Looks pretty nasty.
