I am so very sorry for your loss, my condolences to you and your family. I know you will be giving all the support you can to your Mum now, as others have said your Dad would know that his beloved wife would be comforted and cared for by his beautiful and kind daughter.
I know it is easy for us to say but it is also very important that you take some time to think about yourself, grieving comes in many ways and we all handle it differently. If you need to talk and have nobody close at hand, there will always be someone on this forum that will listen and try to offer you words of comfort and support.
You are in my thoughts
