Re: What should I do next?
There are 3 things I think you should do:
1) Go to a good gynecologist to explore and hopefully treat the cause of your very heavy periods, as there are many possible causes. If no cause is found, going on birth control may help.
2) Get your iron checked! If you are bleeding like that, you're probably anemic, and anemia can cause hair loss all by itself.
3) Go to a high-class hair salon or wig or hat shop. If you know another woman who's suffered hair loss, she may have a recommendation. Find a stylist who will help you develop a look that works for you. I had a friend in college who lost almost all her hair to alopecia during sophomore year, and for quite a while she went around in these gorgeous hats with just this slim little fringe of hair sticking out the bottom. Many people did not even know! Then, senior year, her hair all started growing back.
Regardless of the cause of the hair loss, it's clearly taken a major toll on your self-esteem, and that should be treated also. Counseling can help.
