Increased thyroid. It anything serious?

Hello Doc! So there are a lot of problems that I am facing at the moment. I’ll move ahead step by step. 1. Delayed period- I am 8 days late on my period, though I am not sexually active. 2. On and off anxiety and pain in different parts of body, eg: wrist, thighs knees and sometimes swelling in hands & feet. 3. Puffiness under eyes & face. 4. I feel tired and lethargic many times even if I have taken proper rest. My Background: I have a desk job, I do not exercise regularly. 10-15 minutes of walk is all that I do. I have normal diet, but I eat out 2-3 days every week. I sleep late at night & sometimes I have to force myself to sleep at night. I have been suggested that I may have high thyroid, for which I got my complete blood and urine test done. I am attaching my reports. Please take a look & suggest what is causing all this? Is it anything serious? Do I need to take medications or just a healthy life style could mend it. Please give me a detailed answer.
