Need advice on how to handle my emotions

Tell you the truth, I joined Buddhism in search of peace and harmony. Not because I have mental issues. It is about admitting what I see and feel. I am not that much aware of stuff, but sometimes I aspire to be Buddhist; at other times, I am very emotional. At times I cry because the world is not aware of the basic values of humanity. When I choose to go to the Buddha for refuge, my family thinks that I am a psycho.. When I see others losing human morals, I suffer! Today I feel a bit better than yesterday, but when I look at myself during meditation, I feel like a person who suffers. It is not at all that I am different or I am trying to be different. I want to know the reason for this according to Buddhism?
