Thought ideas for motivation and energy

Hi. I have ongoing feelings of feeling stuck and like I am weighed down in heavy glue. I have low energy and motivation. I am on medication but still have these ongoing feelings. I want to feel highly motivated and energetic. What new thought suggestions do you have that I can practice thinking? I try “I am an energetic person” or “I am motivated” but it feels like a low quality thought. Thank you so much!
