How can one reconcile acts of obedience and striving for God's pleasure with a constant feeling of inadequacy and internal dissatisfaction, especially when suffering from social problems and pangs of conscience due to isolation?

A Muslim must perform good deeds and draw closer to Allah, and he should let the fear of punishment and shortcomings prevail so that he strives to please Allah, while also having a good opinion of Allah and being optimistic for good, as Allah Almighty says in the Hadith (definition) Qudsi: "I am as My servant thinks of Me." It is not proper for a person to consider himself wronged, for Allah Almighty says: "Allah does not wrong people at all, but people wrong themselves." And one must beware of cutting off ties of kinship, and it is not incumbent upon the one who maintains ties to engage in gossip.
