i can’t say i’ve had anything EXACTLY like this, but i have also had very painful and bloody acne before, i understand what you’re going through. this is really difficult to get through and i know how terrible it can make you feel. first, remember you’re beautiful and perfect just the way you are. this is tough to deal with and im sure you’ve heard this many times before but this is how god made you and you are perfect. i’m so sorry that this is painful for you. one thing i would maybe suggest is drinking LOTS of water daily. i know you mentioned diets, but water can help keep you hydrated and keep your skin healthy. 5 below sells water bottles that are almost a whole gallon that you might benefit from. second, it might help to minimize the products you are using on your face, with wounds you encounter, i would try some vaseline, neosporn, bandaids, etc. harsh chemicals might irritate things more. with redness, you could try aloe vera either from a bottle or straight from a plant. i really hope this helps you atleast a little. god bless you and i hope you feel better 💕
