BPD advice

For the past year I’ve noticed my mental health declining and I believed I was depressed for about 9 months. But recently I learned of BPD and it sounds more like what I’ve been going through. My feelings split sometimes within a minute. Eg. One minute I love my boyfriend and the next minute I dislike him. Even tho deep down I love him very much. Same with my friends, I’m always having split change of thought about them. And the depression I believe I was in, was part of a split. I have been reading and watching videos about BPD and the different types, and think I could possibly be interalised. Is anyone diagnosed with BPD and or is anyone else in a similar situation. Thanks in advance.
