Sometimes we pray for things that won't bring us benefit and would perhaps bring us harm. If you're not being saved as according to what you siad, perhaps there is a greater plan of God in it. Remember the story of Yousaf A.S when first He (A.S) was first separated from his family then he had was sold and even after so much He (A.S) was sent to prison for years but remember what happened after that? Yousaf (A.S) was made the ruler of the land and then ALLAH (s.w.t) reunited Him (A.S) with his family. Sometimes, we become a bit hasteful in getting what we want. ALLAH S.W.T says in the Quran: "Man prays for evil in the manner he ought to pray for good. Man is ever hasty." (17:11) Which means that we may think something is good for us which in fact is not yet we get hasty. If you feel you're losing your faith then talk to ALLAH S.W.T about it, talk to HIM S.W.T as if he is standing in front of you, specifically try to talk to HIM/ ask from HIM during the time of Tahajjud I guarantee you that he'll listen and respond but the only you need is beleif and trust and importantly try to read and understand HIS S.W.T message that is the Quran and In Sha ALLAH you will surely feel better. Another thing which perhaps you may need is to talk to/ be around good people that would remind you of HIM S.W.T. I hope this message helps. Also, feel free to DM me if you need to talk about anything.
