Assalaamu alaikum Aminata,
(smile) Welcome to this Forum! I am very happy to hear that you are wishing to become a better Muslim. (smile) This is a beautiful thing, and it is the best way to increase our chances of success.
(smile) If you don't mind, I'd like to ask you a few questions, to help clarify why you may be struggling, and also to help see what you might try doing in order to strengthen your iman (I think this is what you meant by "upping your deen"...?).
Who do you hang out with as friends, colleagues, classmates? Do you have any questions about Islam? Do you have any conflicts with family members that you feel might be fuelling how you feel about Islam? Why do you think that your iman might be a little weak?
How many prayers you do regularly? And what do you feel are the barriers to your completing all five? Are you planning on fasting this Ramadan? Do ever read the Qur'an (in Arabic, or in English)? And how often? And do you understand what you are reading? Do you pay any zakat (if you need to)? Do you do anything as a sadaqa (doing some good for the sake of God: some form of volunteering, donating, being kind with others... even smiling to others...)?
(smile) inshAllah, these questions may help us understand how best we can advise you... (twinkle) and may help stimulate your own thoughts on how you can work on increasing your iman.
May Allah, the Oft-Forgiving, Give us the strength to turn to Him.
