No, you don't. What you love is the idea that breaking your body is what leads to results. You've equated pain and progress in your mind. Most people do this. Most people end up abusing their bodies with too much exercise once they are determined to lose weight. Or, more simply, you are high on endorphins after your workouts because your brain is overcompensating for the stress.

Sorry to say, but your hormones are against you and if you choose the work-out-like-a-21-year-old-man route it will be a gruelling uphill battle. You need to condition yourself first. Read up on adrenaline and cortisol. Take it easy, walk a lot.
You lousy kids! Get off my savannah!
