Assalaamu alaikum my sweet lil sister,
indeed what you wish for is what every Muslimah should wish and strive for. I only ask Allaah the most high to grant you the greatness of Imaan and I ask Allaah to make you a very pious strong Muslim sister! amee Ya Rab!
Imaan increases and decreases from time to time......and we all exprience the decrease and that makes us feel so down to an extent that we cry and cry and not know why! subhana'Allaah.
But the Qur'an speaks to each one of us and its message can lift up our Imaan in away we never felt before! alhamdulillaah. So read or listen to the Qur'an and also be around pious sisters as my brothers and sisters already advised you.
Friends are like role models and if you choose the best of them who will help you strive for Akhirah, by the will of Allaah, you shall succeed both in Dunya and Akhirah!!
Also it helps to ponder on all the blessings you have and that would make you do good which in return will increase your imaan.
*I remind myself of this first as I too am going through a period of decreasing imaan

may Allaah help us all!
