Why was I created, and why do I feel a barrier between myself and people, and am I insignificant in life?

Allah created humankind for His worship, to establish His command, and to implement His law. Whoever deviates from this path deserves Allah's punishment, and whoever abides by it deserves everlasting bliss. Allah Almighty says: "And I did not create the jinn and humankind except to worship Me." What you feel as barriers between you and people, and your perception of life's insignificance, are but the fruits of being far from the remembrance of Allah. Allah Almighty says: "And whoever turns away from My remembrance – indeed, he will have a difficult life, and We will gather him on the Day of Resurrection blind." Therefore, you must fear Allah and worship Him, and strengthen your faith through righteous deeds, so you may live a happy life in this world and be amply rewarded in the Hereafter. Allah Almighty says: "Whoever does righteousness, whether male or female, while he is a believer – We will surely cause him to live a good life, and We will surely give them their reward [in the Hereafter] according to the best of what they used to do."
