Hormonal imbalance?

Okay so the beginning of July I started experiencing sudden acne on my face and back and couldn’t sleep at all. I don’t breakout ever and it just started happening out of nowhere. I tried everything to sleep and I go days without sleeping. I figured it’s hormonal imbalance but then every 3 or sometimes 5 days before my period starts I start getting a rash around my vaginal area and itching. Only once did the rash get bad where I had 2 blisters appear but I’ve got checked and I don’t have any STDs. I workout daily, I do yoga, I drink a lot of water daily and I don’t eat junk food, I am a neat freak so my environment hasn’t changed. Has anyone experienced this or knows what’s going on with me (my body)?
