You can still work out if it's just DOMS and not a developing injury. I suggest easing into the routine, as time goes on and you start getting into shape DOMS will be less of an issue. Then you can start to push yourself. In the beginning take it a little bit easy, make sure you don't get hurt, make sure you build that habit and you'll definitely be able to stick with the new routine.
I feel like a lot of people burn out in a blaze of glory at the beginning because they are so ambitious. So definitely try to be gentle on yourself for the time being
