Hair loss help please

I am 34 years old for the last year I have been losing my hair I have lost about 30-40% of my hair which was already thin to begin with. I have gone to PCP and dermatologist where all labs come back normal we finally did a biopsy on my scalp and found telegen effluvium. Which is "temporary" but typically found in women right after birth or anorexics. I am neither. If I don't find the cause i cant fix it. Stress can worsen it. The only thing I'm really stressed about is the fact that I will be bald soon. I know "it's only hair" some women look fantastic with shaved heads. I'm just not that confident. If you have struggled with this issue and found anything that works please help. I am using a nioxin shampoo system. I use as little heat as possible and only wash about 3x a week. I've made some changes in diet (just adding in some healthier stuff) dr prescribed spironolactone which I currently take 100mg he is about to up the dose. I have opted to take vitamins such as l-lysine, zinc, iron, saw palmetto. Please help I just want to save what hair I still have atleast. This is affecting my daily life
