Extreme fatigue

I am so tired ALL the time and I can’t understand why. No matter what I do, either if I’m doing nothing all day or have been doing something all day, I still have fatigue.

I’m looking towards that I’m anemic because I am CONSTANTLY cold and it’s hard for me to warm up. But I don’t want to self diagnose... when I make an appointment for this problem, what do I say? That I’m suffering from extreme fatigue and it’s messing with my daily activities (because honestly it is)?

I hate feeling like I have absolute no energy 😫.
