Before I started to practise Islam, I used to hang around with bad company, and I mean really really bad company, they used to drink, fornicate-Zinaa, Drugs etc.. And I felt prey to Some of those things. And I felt that it was cool because my "friends" were doing it so I should live an exciting life as well. But subhan'Allah you will never feel satisfied in your heart and you never feel Satisfied if Allah who created you isn't Satisfied with you. If the creator Allah is pleased with you then you will always be happy and content.
And also subhan'Allah when you look at these peoples lives who go out in night clubs and date and drink alchohol, commit Zina(fornication), etc and Have a good time. And Yes So-called Muslims do this as well who have only muslim names and not Muslims at all in Faith. Their lives are just a reck filled with filth and Hardship. They have hard time getting Married, they get divorced even if they find someone to Marry and Most of the Time the Person isn't even a Muslim who they get married to, they have children out of wedlock via Zinaa. They have no support from their families, At the end they get used and abused by their children and people who used to be around them and then they die and no muslim does the proper Islamic burial for these people. This is how these people live. And what a shamefull way to die, and their children at the end, end up in other beleifs and religions.
I don't know about your situation but the people I used to be with, One of them commited Suicide by over-dosing on Alchohol, the other Has his girlfriend Preganent who is also a Muslim wal'Azobillah and works in a Gas Station, the others have just ran away from their parents. This is the life which these people choose because they wanted to have a Good time and have fun.
At the end like I said, You will never be content until the one who created you is Satatisfied with you. And how is he Satisfied with you? By following the Quran and the Sunnaaah and holding on to it by your teeth. And if you don't follow Islam then Allah will make your life so horrible and disgusting and Hard that even in your grave you will be feel remorse.
