6 month old

Ana
My 6 month old baby has two little teeth she is exclusively breastfeed and well she bit me for the very first time yesterday and I screamed pretty loud it scared her !!! Now she doesn't wanna nurse . I read about nursing strikes . But I'm worried that she might be done breastfeeding she jus5 refuses ! she refuses my breast and bottle at all cost . (She does nurse a little at night tho ) she will go for it and then start crying when she notices it my nipple 😭 
I have been feeding with syringe 
She also was diagnosed with the flu she's been feeling crappy since Sunday night but she started nursing pretty good Thursday and is  just now is getting better and playing again .
I don't know what to do I'm getting sad I feel rejected by her . 
I don't know if it's because I starled her or because she just still feels crappy 😓😔😔😔😔😔
