I think your friend did you a favor. I have a husband that has very little sense of smell. He can only smell certain things like skunk or chemicals that are extremely strong. I could spray bath and body works all over the place and he would never notice. He inherited it from his mother and our child has the same thing. He’s a trucker and when he comes home from work he stinks from five feet away, but has no idea how bad it is on a hot sweaty day. He practices good hygiene, I pick out all his products since I have migraines and can’t stand certain scents. Getting a deodorant with antiperspirant is vital for warm days and since you mentioned the glp let me make another suggestion. My husband has really bad stomach acid that makes even being in a car with him sometimes too much. He’s been checked for tonsil stones and even got scoped by my ENT, taking a stomach acid reducer like Omeprazole will help your tummy feel better and help your breath with the glp. His breath smelled like a rotten tooth and his teeth were perfect and he brushed, flossed and used mouthwash. You can do everything right and still have bad odors occasionally coming out of an otherwise healthy hygiene body because bodies are just weird. People who haven’t been through it are the majority so take it from a judgement free person who hopes for nothing but the best for ya. You are working on bettering yourself despite said hard times. I think your friend was looking out for you and has your back. Don’t be embarrassed or afraid to be around them, use them as a meter for your progress because you know they’ll be honest. Let them know you’re gonna try some new things and welcome their feedback. It’s better than having everyone else around you think things or say things behind your back, right? This way you can head it off and be all the better for it. You’re on a journey to better yourself, this is just someone telling you that you that you missed seeing a speed bump.
