Am i really out of shape?

There's no way that you're out of shape. There must be something else going on. 5'6" and 145 is pretty ideal, and you likely have some muscle m. Anybody 5'8" and 119 clearly has no muscle at all. I'm 6'3" and weigh 220 pounds with very little fat -- I work out 5 times per week and carry a lot of muscle.
