If it hurts to lift the weight up toput it onto the barbell use the other arm! Seems simple enough right?
Use hammer strength machines for legs that have weight stacks. All you have to do then is move a pin. Do cardio and abs.
If there's a will there's a way. You seem to have lost the will otherwise this thread wouldn't have been needed. No disrespect but You're the reason you're not exercising at all not your elbow. Just being honest here.
