Hi Maggie welcome of course your scared what a shock for you. Yes chemo is hard actually any treatment is hard and we all have different reactions to the drugs.Make contact with your breast care nurse they have a wealth of information and you can order my journey kit from this site.
There is a young womens group that might be good for you to connect with younger women. There is a lot of people on this site at different stages of treatment to help you.
Wigs it depends where you live, there are places in the city I'm from the west and I went to a hairdresser who is set up for this.
Sending you a big hug it is a long trip but you will get there.
PS ask your breast care nurse about the look good feel better program worth doing, take care
