Does any one have my problem?or is it just me?

I have trouble letting go of my past not the people but the feelings i had experienced with or near them.For example my middle school best friends gave me a feeling of independence and joy i can still remember the good feeling fun feeling .Also some of the smallest like holding hands not just boyfriends but greetings handshakes and hugs i remember they don't go away its been a long time even childhood dreams and hideouts .They just don't disappear is it normal or what some people meet someone and completely forget the next day who they ever were..........???
