Bad Memories

When i was around five years old, a close family friend regularly sexually abused me. I am now almost 14 and suddenly these memories are all coming back. I can't focus on anything and have random 'flashback' type things brought on by tiny little things, which, before now, I completely oversaw. I talk to a few of my friends about it and I can't seem to get it off my mind. Some of my friends have told me to let all my feelings out, to cry or whatever, then some tell me itll only make it worse.

This man was my neighbour and still lives next door/

I have no idea what's happening to me. When I think about such events I begin to itch all over and it has resulted in sores on my arms and legs.

I have had to leave the room many times in school because I remember another thing and get on the verge of crying. My friends are all worried about me and I feel guilty that they have to worry when they all have their own concerns, wich are no more important than mine.

I've become a lot louder than usual to mask the fact that I'm so scared and worried. My friends have told me to see a professional, so, here I am. What can I do to take my mid off these experiences?
