Caring about one's looks is not being vain about the least, so please don't think you're being vain. You're not. Cancer treatment ages the body, and the affects of no oestrgen are felt across the whole body, and particularly on one's face. While I did not have to worry about my fertility as a result of treatment, I did go through a premature menopause and was on HRT which really did ensure I kept my looks and was largely wrinkle-free. I had to stop this when I was diagnosed with cancer, and believe me, I am way more upset about this than cancer. Thankfully, due to the premature menopause, I had already taken up weight lifting several years ago and was in great shape. I know this definitely helped my body deal with chemo, and would have struggled far more if I had been less fit.
I have had a few people tell me I shouldn't care about losing my hair and breasts because I no longer have cancer. I mean ffs, I have to live in this body for however long I have left. I want to like my appearance and not avoid the mirror. I know exactly how you feel, and truly feel for any woman going through this, particularly one who is young. I read somewhere that breast cancer is an emotional emergency and I truly think it is. At points during the illness and treatment, it rob of the very physical characteristics of what society believes a woman to be. The bottom line is that unless someone else has been through what you have been, they really have no place to offer their opinions or tell you you're being vain and should just be happy that you've survived cancer. It's not as simple as that anyway, there's always the constant fear it will recur, and I for one would rather worry about my looks than give head space to something I cannot control. How I look is something I can control, or at least try my very best to do so!
Re. tret. Because I had to stop taking HRT, my skin because very dry before I even had surgery. By the time I started chemo, I had been without HRT for a good three months. My oncologist told me that chemo would make my skin drier, which it did, and much more sensitive, and suggested that I finish chemo before I restarting at a much lower dosage.
One of the perversities of breast cancer treatment is that it usually leaves the individual looking far more unwell than they ever did prior to it. I feel like my entire face has dropped, and not just because my lack of hair means I can no longer pull my hair back which in turn, keeps my face in place! I also feel strongly the other posters don't quite understand what you're going through either, or just how treatment for breast cancer (or any cancer full stop) ravages even the healthiest and youngest of body's. If you have a Maggie's Centre local to you, contact them as they have courses about skincare and other ways to look after yourself during treatment.
Lastly OP, if you haven't already, contact Macmillan and or Step Change re. any financial issues. They will be able to advise.
I wish you nothing but good wishes and that you do anything and everything that is going to make you feel better about yourself. Sod everyone else. Much love ❤️
