What might be the reason for you feeling like this? Have you encountered some problem or issue that is making you feel this way or is this just a general feeling. For the former, its normal to feel empty when we get trapped in lots of problems. Actually that's one of the purposes of such problems(tests) to see if we can rise above them and become more inclined towards religion OR lose our way. At times like this its better to see some motivating stuff and read up on the lives of holy personalities or their companions to see the level of problems they faced. The important thing is to keep on remembering that Allah(swt) loves us; that's the best hope and remedy to remove that emptiness. Some advice for curing grief: 1.Take a bath with cool water, and especially pour it over the head; Imam Ali (a.s.) says, ‘Whoever has grief that he is unable to identify, let him wash his head. 2. Wash the clothes and remove bad smells, which means cleanliness in general; Imam Ali (a.s.) says, ‘Washing one’s clothes takes away grief and sorrow. 3. Mention Allah a lot, especially by saying “there is no power save in Allah”; the Prophet (S) says, ‘saying “there is no power save in Allah” has a cure for ninety-nine illnesses, the least of which is grief. Imam as-Sadiq (a.s.) says, ‘If grief increases, you should mention “there is no power save in Allah.”’Take a bath with cool water, and especially pour it over the head; Imam Ali (a.s.) says, ‘Whoever has grief that he is unable to identify, let him wash his head. ref:http://www.al-islam.org/better_future/61.htm The Holy Prophet said, 'The believer is like the earth: people obtain benefits from it while they are on it.' Whoever cannot endure people's harsh rudeness will not reach Allah's good pleasure, because His pleasure is closely linked with people's antipathy.-[lantern of the path] For the latter you just have to wait it out, maybe its just the evil whispering of Satan to make you feel bad. Do some positive activities and try to talk to some wise people who would transfer their good energy to you.
