Breast feeding hell

Ladies I really need your help. I'm breastfeeding my daughter. She's 3 months. My supply is low and I really need to boost it. I've order tea they worked but not for long trying a different one due to come tomorrow. I'm having to top up as she only Gaines a pound in 3 weeks. I want to get to the point I don't need to use a bottle or two a day. I would feed her all day but it's not enough, I latch every time she's hungry to the point I would be sore and then top up

I had to stop at ,6 weeks with my second born. I really don't want to stop BFing it's been amazing to get to three months. I'm devastated. I eat fruits. I drink nearly ,2 ,1/2 litres of juice with coconut water added in aswell. I'm eating protein. At one point I manages to get down to just a night bottle and it worked. Please ladies I'm so low :(
