What is happening with me?

I am 30 years old, I lost 30lbs without trying over the last 5 months, my hair faills out, I am tired all the time, do not want to be touched in any way, cry for no reason, and feel stress. I have gotten a physical and said thyroid is fine but have not went to gyno yet. I feel like it is depression but my therapist seems to think it is more than depression. I wonder can a 30 year old start going through menopause? I ask I just don't know what else it could be.
