basically i have two different types of ways of being when im attracted to someone. One of them is when i get completely obsessed with the person, i schedule my life around their texts, i create what i call “false memories” of them, where i envision us doing things together that cause me to become attached to who ive made them to be instead of who they actually are. ive only felt this way about someone a few times, it sends me spiralling. The weird thing is its always a love at first sight (one sided) and i dont even know them well!! but im obsessed!! every small cue that theyre upset/annoyed etc will make me so depressed, i start thinking no one will love me, im unlovable, etc. an example is if they leave me on read, ill start being all depressed but the moment they text me, im happy, blushing &amp; beaming like nothing happened!! i also cannot control myself from trying to find every single detail about them and their lives, i become fixated and start collecting “facts” .

is this common?
