Needing a wig

I was diagnosed with breast cancer 5 weeks ago!. 
This was a shock for me as only in my early 40s  and a young mum to a 5 year old girl. 
Iv had mastectomy and unfortunately need further treatment involving chemotherapy and radiotherapy. 
I suffer with confidence within my self and struggling to come to terms with having no hair!. 
I need to buy some wigs which range from £400 to £1000 this is a lot of money for me with not being able to work due to health. 
I would really appreciate if people would help me in rising money to help me buy 1 or 2 wigs. 
Many thanks
