Alhamdulillah you're doing well physically, bun! The emotional rollercoaster is SO normal, a few of us mums with twins went through the same thing, hormones + anxiety about managing two babies at once = quite a lot lah. Dekat confinement period especially ramai yang experience mood swings, so don't worry you're not alone! If it gets really overwhelming or you're having persistent sad feelings, best to mention to your doctor or midwife ye, just to be safe. In the meantime, lean on your support system, sometimes talking to other twin mums helps, they really get it!
