This feeling of being out of touch with religion of Islam can be one of the results of sinful acts which were not been forgiven yet. Shaitan who is our worst enemy keeps on trying to whisper in our hearts to drive us away from The Right Path which is the way of Allah, where we can never succeed away from it. Those who listen to and follow Allah have the peace in mind and heart, while those who listen and follow Shaitan, have the bad effect of that on their hearts and minds.
I advise you to try your best to clean your heart and mind from the filth of sins by deciding to leave all sins and by sincerely seeking forgiveness which purifies us from the evil effect of sins.
It is also very useful to recite Salawaat which enlightens our hearts and keeps us away from Shaitan. Also it is very useful to repeat saying LA HAWLA WALA QOWWATA ILLA BILLAH.
Reciting Quranic verses and Du'a and paying Sadaqa help a lot.
If you can visit a grave yard where any one from your family or friends is buried, that will also help in purifying your heart and mind.
