Are men more important then women? I had this question for a while and I just can't find the answer. Whenever I go to church all I hear, is that boys can do this, that and other things, but the girls can only listen and sing. It makes me feel very sad and depressed since I feel like I'm only an object that men has in order to not feel lonely .
What you referring to is Complementarianism.


  Complementarianism is a theological view in Christianity [...] that men and women have different but complementary roles and responsibilities in marriage, family life, and religious leadership. [...] These separate roles preclude women from specific functions of ministry within the community. Though women may be precluded from certain roles and ministries, they are held to be equal in moral value and of equal status. The phrase used to describe this is 'Ontologically equal, Functionally different'.


This includes the concept of male headship, but does not mean that women are less "important" than men. It only means that they have different roles. You can take a role that falls under the responsibility of men, and then use that to say "women are less important". But that would ignore the whole picture, where both women, and men, have important roles.


  I feel like I'm only an object that men has in order to not feel lonely .


This is certainly not in agreement with complementarian views, which, correctly understood, neither objectifies men or women. Furthermore, your roles and responsibilities extend far beyond making someone "not feel lonely."
