Medication combination

This is VERY specific, but wondering if anyone is on all three of these medications at the same time? -Wellbutrin -Zoloft -Vyvanse

Ive been on zoloft & Wellbutrin for a bit now, but now my dr has perscribed vyvanse as well. But now after reading online, zoloft & vyvanse shouldn't be taken together? But if that was truly the case why would my dr perscribe it? (He is the perscriber of all three meds) I will contact the practice when they open, but curious if anyone else is on all three!
