Trust

It takes months to build a great friendship. But also seconds to destroy. Everywhere I go I seem to find a great friendship then destroys in seconds. What do I do? Keep trying to find a better friendship. Or do I back down and give up. Many people try to break me down but fail always occurs upon them. If you say crap to me I will say more crap to you back. Sometimes I make stupid decisions but doesn’t everyone in a relationship? I’m so confused and I have absolutely nowhere to go. Trust is a main key in a relationship with someone. But I just don’t have that yet.
