It's so hard

Trying so hard to only breastfeed but I am SO exhausted.... She wakes up literally every hour or 40 mins to eat. And at night she will last up to 3 hours of like 15 min naps and eating . During the day my aunt comes over to help out with her and watch her while I sleep but she still has to wake me up because the baby is hungry. At night I can barely keep my eyes open and I know it's 'unsafe' but I'm constantly falling asleep with her in my hands , I just can't do it. 
Would it be bad if I introduce her to a bottle right now ? Will it effect her latching on ? What if I bottle feed and breastfeed but only bottle feed when someone else is taking care of her because during the day I have no problem with it, it's just at night I'm so tired.. 
Does anyone else so this ? Please lmk 😥😞😒😒
