is it just mine or do strings on stratocasters break more than on other guitars like i also have an epiphone sg and the strings dont break nearly as often on it
Strats are longer scale so tighter for the same tuning. Strats go out of tune if you look at them wrong so you are forever tightening and re-tuning them. Strats have a trem system that alters string tension a fair bit. I'd guess your SG is hardtail.
I pick up my guitar and play
Just like Yesterday

T C Ellis Series 2 LP w/Skatterbrane Quiescence pups
Cort EVL-K6
Yamaha RGX211 modded
H&S Electric 12-string
Shaftsbury Ricki 4001
'84 Fender Yale
Roland Cube 15x

are you using the same guage, and same amount of playing time, and most of all, tuning?
Just call me Julius, J, etc.
Taking an Internet break for a while, will come on when I can.
