Friends mother died and I’m falling back in love with her?

Sexuality is very fluent, and (sorry ahead of time, but I will explain) religion is very stagnated. Religions, especially Christian related ones, have trouble accepting that people of the same sex can engage in emotional or physical relationships. Finding attraction to someone of the same sex is a completely natural and normal thing to experience, just as finding such in one of the opposite sex is. Some people even find attraction from both sexes, in either one or both of these areas. It doesn't mean that there is anything wrong with the person, it doesn't have anything to do with 'sinning', it isn't going against god's will. It is what it is, and honestly, I feel that there is way more stress put on it than necessary. The way I see it, it's like saying that preferring a flavor of cake is forbidden. "Why can't I have carrot cake?" "Because they said God doesn't like it!" Utter nonsense, respectfully.
Now that aside, there is also the factor that not every relationship involves sexual activity. Love comes in many forms, a lot more forms than I am sure most people realise, and one form of it is through an emotional relationship. Just because you emotionally love someone doesn't mean that you are going to have sex with them or that you want sex with them. It's more of a love that resides on the levels of inner feeling and comfortability with a person, someone you can connect with and feel free emotionally with. The way you describe the feelings you have for your friend, it seems that you deeply care for her, deeply enough that you fall in love with her to the point where you would do anything for her, because you love her. And I also feel that, you feel restricted in the amount of love you can express towards this friend of yours, due to several reasons that I need not explain here.
The thing is, it appears to me as if you are attracted to your friend enough to feel interested in her. And now that her mother has died, you know that she needs people in her life to be there for her and support her. It's human nature to care for another who you feel is in need of care. And since this girl is someone you are interested in, you feel all the more obliged to be the one who is there for her. Not that you have to, but you want to.
I would also like to say that it is nothing to be ashamed of or neglect when you feel such things for another girl. When you feel such things, it is for a reason. Allow yourself to be free with your feelings for her, and if you deem it right to do so, don't be afraid to let her know how you feel. You would be surprised how much it opens a person up to new things when you tell them something from your heart. And for all you know, she may even feel the same way about you.
I think it is very sweet of you to be so caring and thoughtful for your friend. I am sure she will appreciate every little thing you do for her, and to show her that you are thinking about her. Maybe even plan some time with her, simply going out for coffee or even inviting her over to your house to watch movies or something similar to help her get her mind off of the loss of her mother. Everything you do to help, will help, and I encourage you to do so :)
Oh, and don't be afraid to express how you feel towards her. I am sure she will appreciate having someone who feels as much for her as you do, especially after the loss of her mother.

Thank you so much, and yeah no harm done, I completely understand what you mean about the religion thing. It's just hard to break free of the the ideals once they've been instilled in you for so long. Yet again, thank you so very much for your thoughtful advice and commentary. I will definitely try a few things out, not sure if I should tell her just yet, but I'll definitely look into it. Last time, thank you very much for taking time and helping me out, it means a lot.

Thank you, I am very grateful for so much gratitude :) And yes, I understand what you mean by it being tough to break away from ideals that have been instilled in you. It usually takes a bit of time, and some willpower. But I believe you'll be able to overcome these obstacles n.n
I wish you all the best, and may something beautiful blossom from this experience :)
