better to be alone or having friends??

If we are alone, we will feel lonely except if we are 'heartless' and comfortable when we stay alone. Having friends is really wonderful. People always say that it is a special gift from Allah to us. However, we may get problem if we are not taking good care of our friendship. Actually, there should not be any misunderstanding between each other. At the same time, don't let the friendship makes us stress. For example, when we always ask for a help from our friend but we don't know that he or she is having problem. This will make he or she becomes stress with the friendship. People always say that everyone never escape from doing any mistake but I think if we are in that kind of situation, we will not conscious about that. He or she maybe can only stand with us without saying nothing. I also feel the same situation where sometimes I think that I am not doing it sincerely. Then, if we are not doing it for him or her, they may be broken hearts then. So, we should think about it carefully if we don't want it to be prolonged...:(
