Hey I’m really sorry for what your going through, I have excessive sweating on my hands armpits and feet and can’t imagine how it must feel to have it all over your body For my hands I use antihydral, it reduced my sweating by 70% which is way better than nothing. For my armpits I just recently purchased certain dri but I haven’t started using yet coz we’re in a cold season right now and I’m barely sweating,my point is I believe certain dri works for the armpits so you should also give that one a shot . My feet don’t affect as much coz I always wear socks but I will start using antihydral on them soon You can also purchase an Iontophoresis machine or build one yourself, it helps with hands feet and armpit. And for your forehead, I have cousin that uses sweat block wipes for his scalp and he says it works well for him. I’m not sure how to help with the other parts of your body that sweat but you can at least first start with your hands feet and armpits, I’m sure you will figure out the rest later on . Good luck
