Hi Tracy. I'm sorry for your recent diagnosis. Believe me, you are not the only one who has gone through these feelings and the uncertainty. Some people do not lose their hair, so there is a possibility you will not have that transition; however, I would try to prepare for it.
I would suggest getting signed up for a Look Good Feel Better class through the ACS (you can find it through the Support area of the ACS website). I'd go sooner, rather than later. I waited until I was on cycle 4, which was 3 months into my treatment because of scheduling conflict and when I went it was GREAT to be around other people going through similar situations and getting tips and asking questions. Some people had recommendations for where to get a wig and I wished I had gone to their person instead of the salon I went to.
Other than that, hang in there, reach out to this community or your friends and family whenever you have questions or need support. This website has been a wonderful resource and I have made a great friend on here. We help each other through this. The bumps an the celebrations.
Do you know when you will have your first treatment? I was very apprehensive about the Chemotherapy and I've been very lucky that I haven't had any of the nasty side effects that I anticipated. There are great medications that your oncology team can give you for so many thing.
Keep your positive attitude about beating this cancer. And Welcome to the community.
