Hello Yes I Need Help. For 2 Months My Heart

Hello yes I need help. For 2 months my heart rate resting stays around 100-108, when I get up and go about my normal routine it gets up to 120-130 and my heart rate it a norm 80-85. I'm normally very active in the garden with my g babies and on the go. But not anymore. Also I get dizzy and feel when talking I can't get enough air and I'm tired all the time and weak. Finished test this week. Had a echo stress test, a cat scan on my lungs and heart and all have came back good. Had lots of blood work and all is good. So I'm still dealing with exhaustion , rapid heart rate being tired and no answers. I feel like crying. I want my life back. What's next? Where do I go from here? What test should I have now?
