Oh, same here.That's why in my fanfic (that hasn't left my head yet) My Shepard Lynn survives the Synthetic Beam jump and has to find Kaidan( She eventually does)
I toyed with the idea of having one of my multiplayer characters make that sacrifice of life while Shepard pleads to take the burden upon himself, but is too badly wounded to outrun anyone - but ultimately decided destroying the Reapers was best for reasons not as shallow as "Shepard lives"
