Hi Focus, nice to have you in the forum but not under the circumstances. Welcome!
Loestrin is a birth control pill, is that right, I looked it up. Its beyond frustrating when our GP's don't listen to us and its very common plus they have no idea the panic and ongoing anxiety they cause. Drives me mental and I get quite angry about it - my own GP has been guilty too.
Please give us some more information about yourself, like how old you are, why you are on this particular pill, what your symptoms have been and how you have come to the menopause forum, any treatments you have had in the pat. We would like to know loads about you in general anyway but in order to advise what to say to your GP or provide you with ammo to take with you we need to know more about how you find yourself in this position.
Meno and anxiety are terrible to deal with generally, having PTSD as well must be terrifying in the feelings your body can produce I am so sorry that you are feeling this way. Anyway there will be plenty of words of advice and comfort coming your way soon - just tell us more.
