If a sick person doesn’t realize that they are sick, the doctor will never be able to cure her. So realizing that there is a spiritual sickness is a sign that your faith is strong. I have the following words of advice for you:
Al-Haakim reported in al-Mustadrak, and al-Tabaraani reported in al-Mu jam, that the Prophet (peace and blessings of Allah be upon him) said: Faith wears out in the heart of any one of you just as clothes wear out, so ask Allah to renew the faith in your hearts. (Reported by al-Haakim in al-Mustadrak, 1/4;. Al-Haythami said in Majma al-Zawaa id, 1/52, It was reported by al-Tabaraani in al-Kabeer and its isnaad is saheeh. ) This Hadith tells us that our faith will become weak but we will have to strengthen it with various actions and different good deeds. If we try to implement the following, In Sha Allah it will help us all.
On a weekly basis, try to attend some Halaqah or an Islamic gathering. That is a great way of keeping the battery of Iman and actions charged.
A good suggestion would be that you join some weekend or evening Islamic course or something of that sort. You will find good company there which will be a means of strengthening your faith and Iman. And when you feel like you are all burnt out , there will be others there who will guide you and help you out and get you back up on your feet again.
Try to read some portion of the Quran everyday and make Zikr of Allah. It will not be a bad idea to start off the day by reciting Surah Yaseen.
Try to have a daily Halaqah of reading from a Hadith book at home. The most widely used Hadith book in English is probably Riyadh us Salihin. Set aside a time at home, and try to sit down with other family members. It does not have to be long. Even five minutes or ten minutes will suffice. A daily dose of the words of Allah and his beloved Prophet Sallallahu Alaihe Wasallam goes a long way in keeping us attached to our faith.
After prayers or whenever, try to recite as many times as possible the words which are mentioned in the following Hadith: The Messenger of Allah (peace and blessings of Allah be upon him) said: Do not forget to say in every prayer, Rabbi a inni ala dhikrika wa shukrika wa husni ibaadatika (O Allah, help me to remember You, thank You and worship You properly.). (al-Nasaa i, 1303)
