Mounjaro 2-Month Review

Everyone I see asks me if I'm sick...
I was 181cm and 85kg, but I am currently 68kg.
Since I don't do any separate muscle training, even I can see that I've lost muscle mass.
A senior colleague I met today after a long time asked if I was sick and told me to go to the hospital....
Since there were other people around, it felt a bit awkward to say, "I'm taking Mounjaro." So I just said I was on a diet.
They told me, "You can't lose that much weight in such a short time through dieting. You absolutely have to go to the hospital," lol.
So I just messaged them on KakaoTalk saying it's my 2nd month on Mounjaro.
This person doesn't even know what Mounjaro is lol.
Even though I told myself to eat at least one proper meal for lunch, I end up leaving food behind at the cafeteria ㅜㅜ
Since my appetite has diminished so much,
I get dizzy when I stand up after sitting down, so I'm planning to stop now ㅜㅜ
I had a health checkup last week, and my blood pressure went from 150-98 to 110-70, and my liver enzymes are all normal.
Is the medication too effective...? It's good that my numbers improved, but I have no energy, so this is it for me ㅜㅜ
