You're not being silly at all! Your experiences are yours alone and they are important for they mean something to you. I don't even know you and I wish I could take your hurt and your suffering away. Perhaps your friend doesn't understand the full extent of your pain and may never will, don't let it into your heart-what they said, some people just don't know what to say. Some people can't muster the kind of words we are waiting for, and maybe they are troubled by it so much that they wish to blow it off because they don't want to beleive someone would make you hurt so badly.

Whatever the reason, I'm sorry , and know that we here all know you're struggling and although it cannot replace a good friend, this is a place of support and it'll always be here in that way!
