I get the feeling people with these same disorders will understand what I am going through, and I really feel the need to share. Every time I've fallen in love with someone, or what feels like loving someone, it is extremely overwhelming and detrimental. I fall for people extremely fast, and when I do, the feeling is beyond intense. That person consumes the vast majority of my thoughts, and I get a hypomanic and general high for awhile. My mood completely depends on that person and how I feel they are attached to me at a given time. A text and subsequent constant communication will give me a high and make my day, and lack of will send me spiraling, especially if it's prolonged. I get extreme anxiety if I feel there is any threat to my relationship with them, and it can cause me to lash out (this may also be in part due to attachment issues). Hypersexuality is also a big problem, and has definitely caused issues with partners in the past. I will also laser focus on this one person and ignore all other aspects of life, and it becomes chaotic and messy very quickly. I guess I could compare having feelings for  and access to the person I've fallen for as a drug, with the high feeling euphoric and experiencing "withdrawal" without them. This also sounds similar to BPD? I don't want to self diagnose, but all of this makes me a bit sus.
