Questioning my feelings on my diagnosis

Hey everyone! I (20F) Just got diagnosed a few days ago with bpd and was curious if anyone else could relate to how I’m feeling rn. Mostly a little confused, but happy I finally got a diagnosis. I guess I just didn’t expect it. I don’t have violent mood swings like ever. And while I totally have mood swings from happy to sad to anxious (I also have GAD), I’m never angry. I guess everything I feel is just internal. I pull away from people out of fear of rejection instead of forced clinginess in friendships. I have a long term relationship that has always been healthy. I feel emotions so strongly, and I tend to overreact, but I always put negative emotions on myself instead of others because I don’t want anyone to feel mad at me. It’s the worst feeling in the world. And I have intrusive thoughts and sometimes compulsions. I thought I had ocd for a while but my testing results with my cbt clinic told me that it was part of the diagnosis. I guess it’s just hard for me to believe that’s what it truly is. Especially bc I don’t have a trauma background. I had a good childhood. Anyone else relate to this? Do I have the more silent type? Looking for answers from others with this diagnosis and what I can do to help support myself from here. Advice would be greatly appreciated.
