Coping…I've been diagnosed with glioblastoma. I'm 27 years old and I've been given 10 years. I have no support

Hello, I’m 27 and have glioblastoma. I’ve been given approximately 10 years. I’ve had to freeze my eggs and can no longer have children. My family say I shouldn’t have any because of leaving them behind at a young age. This kills me, it’s also like the purpose in my life as a women. I worked in mental health as a nurse and can no longer do that because of it being a brain condition. I’ve got a scar across my hair line and have lost most of my front hair and sides. Can manage a pony and a hat but it’s so irritant. I’ve gained so much weight. I’ve lost my identity, we thought it was going to be a life span of 5 years. 

im struggling most with the hair loss if there is anything anyone could recommend anything I would really appreciate and I wanted my own family. I have no support and 10 years feels like a long yet short time
