You do the feeling exercise the same as always. It might also be wise to check why you are feeling exhausted, are you giving yourself enough time for what you need to do ad recover?
Absolutely no need to ask yourself those questions if you find your feeling and recognise the energy. The questions as you noted are a good way of just starting to feel the feeling. When you feel the feeling send love to it. Love the feeling.
Oh and in feeling tired I notice the feeling is more of a slow, not enough movement energy. Like big load of energy just landed somewhere within me and stopped.
It's different for everyone words cannot describe it accurately nor do we have a way of agreeing on names for it. We tried to do that and that's why we are so disconnected from our own feeling energy.
