Feel so lost...need some advise please.?

It will be a year on Mother's Day that my mom passed away. She found out she had cancer three years ago but didn't catch it in time. She went through chemo but said she had enough and was just tired. She struggled so much with it. I don't blame her for her not wanting to fight anymore i didn't want to see her suffering like that. Cancer is a horrible disease to live with. I wouldn't wish that on anyone and no one should have too. My sister's were wanting pictures of her. So i was thinking maybe i could do a photo album of her in remembrance, but i don't know how my sisters would act on me doing that. It's been real hard not having her around. I know ive taking her loss very hard she was my hero. I would tell her everything that i was going through. Now she's not here for me to get advise from. I would ask my sisters but i want this to be a surprise if i do go through it. I was always the one that took pictures at every occasion. All we have now are memories and i want her to live on with those pictures and for us to always remember her. I really need advise on this...help feeling lost
