Is submitting yourself to the concept of a god not the opposite of introspection? You are forgoing the need to find meaning in yourself and the world around you and instead choosing to believe a pre-made 'answer' to those questions.
To me this is like choosing to throw yourself into a relationship only because you find that you struggle with being single. Using an easier, readily-available external source of comfort found in being part of a 'collective' rather than the more difficult path of becoming comfortable with yourself as an individual.
I believe you misunderstood the concept of submission. In life, worship is inevitable. For instance, people could worship material gains or the longing for the acceptance of society. Whether you like it or not, you will worship something(or multiple things) in your existence. In the act of submission, you conclude that there is nothing worthy of worship but Allah, the creator and sovereign of all worlds.
Part of this conclusion involves introspection. I believe there is a false dilemma in your approach where you imply that you can either find meaning in yourself or follow a 'pre-made answer'. These are not mutually inclusive. In fact, in numerous verses in Quran(the word of Allah), you will find that Allah strongly encourages the reader to sincerely reflect and find truth in him/herself and the world. Allah has given us the gift of reasoning and introspection and we can use that to reach the ultimate peace in submission to Allah.
Islam, being very strictly monotheistic, promotes that true comfort and solace is provided solely by Allah(in submission), not in being part of a 'collective'.
I hope that was insightful. :D
Disclaimer: Don't take my word, or anyone's word regarding Islam, for granted. I strongly recommend reading the Quran with an open mind and open heart.
