thought ladder

I would like some help.
Recently I feel like not doing anything. I don’t have much energy, I would like just to stay in bed doing nothing.
My thoughts are, that I don’t care about anything, I don’t care for results, etc.

I would like to have the thoughts:
I feel glorious energy.
I am active and alive.

But I don’t believe it at the moment. Could you help me with finding some thought that would be more believable and would be taking me to the thought above?
