Is it normal for a girl to feel that people don't want her, along with her pessimistic outlook and excessive shyness?

Among the greatest means by which a servant becomes beloved by people is performing righteous deeds that God loves, for He will love him and make him beloved to His servants. This is achieved by staying away from sins that cause animosity among people. Shyness in young girls may be praiseworthy if it does not hinder them from performing beneficial actions. It is also advised to associate with committed female peers and discuss beneficial matters with them, and not to be keen on the love of anyone other than family and committed friends, lest it lead to evil.
