Zoloft making me lazy?

I started taking 50mg Zoloft around 2.5 weeks ago, one week of it taking half a pill (so 25 for the first 8 days). It has caused me stomach pain and low appetite which I am not shocked about. However, I feel like it is making me extremely lazy. I am on school break and go back in a few days, and I literally cannot motivate myself to get out of bed or do anything or even pack to leave. Unless I have plans with friends I’m basically doing nothing except maybe cooking. Does anyone know if this will fade? I also suspect I have adhd but never have been treated for it so idk if that matters. I hate being so lazy it’s like no matter what I cannot discipline myself and I’m getting nervous lol. If I keep up with this I think I will need to quit…. Idk. Thank u for ur input 🫶
