this might be kinda long so bear with me please

so basically these are my symptoms


* my severe attachment to people - will do everything in my power to stop them from leaving me and everything i can to get them back if they have already left (think stalking, repetitive messaging, messaging on multiple accounts, messaging and stalking their friends etc for literal YEARS) 
* used to dissociate a lot, lots of derealisation  it was quite scary. nothing would feel real and everything around me felt quite dream like, gets worse when i’m under immense stress and mental pressure (started when i was quite young, like around 7?) 
* mood swings, like, intense mood swings. this one time i was so sad that i was crying in class (nothing could ever get me to cry in class) and then fast forward few hours and i was great, i was so happy. another time i was absolutely breaking down sobbing and self harmed and then an hour later did my makeup and felt amazing. ??
* i idealise people a lot. i will go from thinking they’re amazing and i want everything to do with them, to suddenly hating them and distancing myself from them when they do something wrong 
* easily irritable and outbursts of anger over MINOR things

there are a few more but i cba to write them down. i’ve booked an appointment to talk about it with my gp but i’m starting to feel unsure and i’m starting to think maybe this isn’t that big of a deal?? it’s not currently impacting my life that much but it used to  idk it kinda comes and goes idk how to explain it. if anyone has any advice or anything please help
