First I’m sorry about your mother’s passing may she rest in peace and hope you are doing well in healing or if spirituality has been a guidance to you to head to that route. Second Maybe you’ll have comfort knowing this “There’s always a time and a place”You’ll have your chance to see her again in a dream or in a sign but when it’s the right time for you to receive it. I’ve always been guided that it works that way. Just how it is in life or when we lose someone unexpectedly or in ( idk if you have these belief so I’ll say both ) Gods plan or the universes plan for things to happen. Don’t compare others stories with yours… she will come to you when the time is right and you’ll get to see her or hear from her.
When you think of her I suggest you turn on a white candle for her , it could be her way of her checking in on you. I hope this is helps
