Hi Shelley,
When i read what you wrote i feel like we are the same. Im 22 years old and have been dealing with my hair loss for 2 years. Its a hard thing to do, watch your hair fall out and feel like theres nothing that can be done. But like stkitt wrote there is treatment for hair loss. For me it took 6 months for someone to help me. For 6 months no one told me that i could see my family doctor and get the shots administered from him, so i sat by and watched what felt like my life slip away with every chunk of hair that fell out. I got depressed and felt withdrawn all the time, now that i have had the steriod shots a number of times i thought it was over, but as it turns out i was wrong, it can re-occur. Although this time i knew exactly what to do about it, even tho my hair seems to be growing back im still dealing with the depression, anxiety and other effects that alopecia had on my life. But what really really helps me is the support i have, especially from my boyfriend. He kept me feeling beautiful. I really hope that you have support and someone who tells you that your in fact beautiful, cause you are. Never 
let anyone say any different.
