You are not pathetic.It's normal to get upset about losing your hair.I think I was more upset about losing my hair than my boob-how crazy is that!! I was ok at first wearing "stuff"on my head but as time went on into the summer months it drove me nuts cos the hot flushes made me want to rip my hat/scarf/wig off.So it's not just the vanity but also the discomfort.It took along time for my hair to grow back-over 6 months-so I now consider myself an expert in "head management"! Good luck with your treatment-hope all goes smoothly for you.
