I really don't know how to put it. But whenever I lose something, I feel depressed. Let me explain... Two months ago my 5 year old laptop broke down, so I bought a new one which was better in every way and runs Windows 10 instead of XP. But I kept feeling depressed at losing my older laptop. Sometimes when the memories come back, I feel depressed again. I try not to think about it but no one has 100% control on their thoughts, or that's what I think. That isn't the only example, it literally happens with everything even for something like a pen which I only had for like a hour or so. I play this online video game called ARK: Survival Evolved and whenever I meet someone new and he leaves after sometime, I feel really depressed for losing a friend even though we only talked for like a min. It also happens with anime, when I complete an anime I feel depressed that I watched whole of it and there will be no more. I don't know how to explain this but I'll try, I get too attached to things too quickly and feel depressed when they go. Its like a nostalgic depression if that's even a thing...
I have no problem with it and even feel depressed when I think that this depression will go away as I am already attached with this depression. I am just searching for someone to relate to and know if I'm not the only one in this world with this. I still don't understand if you understood what I mean, I feel like the only one who will understand this is the one who has or has ever had this feeling.
