Tears

In my attampt to bring an idea or in perventing something from happening I fear that I have only made it worse.  I tried to change things and people so that things I fear would not come about, but in my conviction and force I have only pushed harder to what I dont want.  I have had the opposite affect of what I wanted to do.  Now what?  Sit back and let people take their course?  How can I do that?  I cant just let things happen when I believe them to be wrong.  I am afraid.  I am so afraid.  I am losing.
