Do you fit the description or definition of Muslim? And do you truly worship Allah, only Allah? If not, then surely you are not a true Muslim, despite your claim and confidence and whatever else. Understand verse 1 to 3 of surah Kafirun, and realize that a Muslim is one who worships Allah, while one who worships other than Allah is a Kafir. Understand that a Muslim is one who "aslim" to Allah. Be aware that a Muslim does not mean one who "aslim" his or her will (to Allah).
And understand the 3 crucial facts or truths regarding worship, which are that to worship means to humble oneself as slave to Allah (not to humble one's will as slave to Allah), and that if there is a slave, then there is a lord, and that a king, as is a master, is a lord, is necessarily a lord over those he rules. Simply said, if you would like to be in Islam or become a Muslim, or if you would like to have a very good relationship with Allah, Him, the Supreme Being, then put to practice, "oh Allah, my creator, only you are my lord, my king, my god, and to you I surrender; salaam, oh Allah, salaam".
