Memories? Just a record

Things are always changing, every part of your actions now will one day be memories. No matter what you do there is no way to have things always work the same way. Instead of having regrets with the past, it is always the best to work and fight hard now because now and future is what you can change, but the pass isn't. I can control what to think, I can control my action, but I can never control my feelings. I always dwell in the past, I remembers so much. I know there is nothing I can do to change those things now, but it always makes me feel sad. The only things I can do is escape from it with musics, or to share the pain. But there will be no one who can. I always think that being special or unique is something good, but having no one to understand what you think is not as fun as I thought. Once you've change you can never go back, is it wise of me to do what I am doing now? Good luck future me for reading this, I'll see what's your answer
