Thyroid issues

[Ihatemylooks12]

So I've some my blood work out of suspicion of me having a bad thyroid and I think I was right, but my dumbass did the wrong blood work and now I got to do it again to check the right stuff such as b12, tsh and something acid idk. I've been feeling cold and very low energy and exhausted like I used to run 3X a week and do some gym 4 months ago and then like my body became slowly shit. Fortunately I went to a doctor and she told me to do my blood work. Things is I am scared of blood work and last time I collapsed on the floor after it like a pussy.
