Always tired

Hey guys. So lately I’ve been feeling super weird and idk if it’s normal or if I should maybe go to the doctor? I’ve been feeling suuuuper tired like I feel like I could sleep for 24 hours. I feel groggy literally all day. I’ve also been feeling super weak and out of it

My head has also been hurting like almost every day, like my head and my neck as well.

Some background info that might be helpful to know is that I have anxiety, I also got the flu shot last week (and I got a cold literally the day after I got the shot so idk if this is another side effect ??)
