How likely is it for adhd and bpd to effect the same person? I was diagnosed with ADHD as a kid and never really had it treated extensively. I always thought I was pretty normal amd after time kinda disregarded the ADHD. im 26 years old, and someone began describing BPD to me and it felt like I was being talked about by someone following me around with a clipboard my whole life. Everything she said and thay ive read seem to be pretty in line with bpd which explains my entire adult life. I am afraid to go to a therapist for them to tell me im normal, or get misdiagnosed and get unessecary treatment thatll possibly make my situation worse. So im trying to learn what I can before taking that step. 

I get attatched to people dumb fast, with anyone Thsts willing to give me attention that I can relate to.. Always want constant conversation with them, god forbid they appear online on Facebook and leave a message on read, I get anxious they dont want to talk to me and start thinking im getting cheated on (no evidence at all) and get angry. Like enough to the point I can physically feel the anger. Logically i know they dont owe me a response or to even read what i say. My anger makes no sense to me.  But it Doesnt change anything. I try not to lash out and usually i do alright, recently anyways. I can spend time all day with them and i already miss them and want to talk to them by the time im back home. If im not talking to them I just feel loneliness to the point of discomfort at times. Im afraid to voice my problems in the fear of doing so will cause an argument and make them leave. Ive let people treat me awful and go back to them multiple times because getting cheated on and lied to is better than beimg alone.. 

Ive realized that Ive ruined many opportunities of good relationships due to this behavior. I never understood why my experiences were so different than everyone elses. I just thought and accepted im not good enough to be in a relationship and im going to be alone for a good part of the rest of my life. Ive got little to no sense of purpose or who i am, near death experiences hardly phase me where others would flip out, I wouldnt say im suicidal as im not going to kill myself. I couldnt do thst to my family... but if it were to happen, I wouldnt be dissapointed. Im tired of pushing away people I care about, intimately and platonically. Im at the point now where I pushed everyone away to avoid the inevitable from happening. Currently I do not feel that i live or survive.. I just exist, nothing more. Ive been like this for so long and Im so tired. Idek where to start.
