Does anyone else feel super nostalgic all the time?

Nostalgia has always been a huge part of my life. I can't even remember a time I haven't been nostalgic. This might be because I had a great childhood, but I feel like I've been feeling nostalgia since I was a toddler. I was talking to my friend the other day about nostalgia and she said that she loves feeling nostalgia because it reminds her that her memories will always linger, and she will forever be an amalgamation of her past experiences, but I do not feel this way at allllll. Nostalgia for me is such a devastating, crushing feeling. I feel so alone whenever a wave of nostalgia hits, because no one I've met feels the same way about it that I do. 

I do like reminiscing on my experiences sometimes because it's interesting to observe my different stages of life, what I was interested in however long ago, etc., but whenever I do it always comes with a huge undertone of negativity. Arghhhh I just wish I could look back on HAPPY memories and feel HAPPY. The understanding that I'll never get to experience certain emotions and vibrations again is just really uncanny to me. I feel even more alone because no one I know feels the same way I do about this! I guess I'm just a very sentimental person lololol
