((hugs))
it will get better i promise
my dd was like this, my let down was too fast for her, there are thing you can do and yes it will get better in time
you can feed leaning back/lying down, with baby on your chest as this slows the flow of the milk
you can express a little bit off first as this releives some of the pressure and the fast flowing milk (this is what helped me the best, although i appreciate it is not practical to do anywhere other than home)
i also found feeding from only 1 side and using the same side for a 4hr block (whether that meant 1 feed or 4) helped too.
which helpline did you call? there is the NCT breastfeeding helpline who have councillors who can come out and see you feed, there is also the la leche league who may have a group local to you that you can go along to, i found them very helpful.
also have a look at kellymom.com i found some good adivce on there
i remember how awful it was and i thought about giving up many times, BUT it did get better, your body calms down a bit and as baby gets bigger they can cope with it better. i think we were pretty much a-ok by about 10/12 weeks. dd is now 13 months and still feeding
you are doing a brilliant job, well done and stick with it it will get better if you want to CAT me feel welcome to
