Processing Strong Negative Emotions

.I often feel a lot of anger and strong negative emotions. My anxiety makes me feel super irritable. When I had PTSD symptoms - triggers would make me feel like I had to fight for my life and I would feel very angry as well. Hatred and resentment. I feel like it just builds for me and I can’t seem to ever get over it. Journaling about it or talking to a therapist is really the only two things that have helped me. Confronting the person usually doesn’t help me because the conflict I have is usually with a person that has an Avoidant personality disorder or a narcissist. Talking to other people about it (who are not licensed therapists) usually doesn’t help and often strains your friendship or relationship with them. They just see you as a complainer or someone who is obsessed or even delusional. Most people and even some therapist - are not well equipped to help you work through these issues so I wouldn’t even try it. I also have had some benefit with online courses specifically about emotional eating and personal accountability which surprisingly did help. I never completed the one about depression that I tried so I don’t know if that would have been helpful or not. Sadly, I think the world is full of people with personality disorders or I just attract narcissistic people because I’m an odd mix of strong person but low self esteem. Either way - two years ago I finally started to isolate myself from everyone as I realized I was constantly putting more into relationships, friendships, family than I felt I was getting back. I took the time to step back and realized that almost everyone that I loved has failed me in one way or another. It’s hard to accept that. It threw me into a deep depression and then I got pregnant - on purpose it was planned but I didn’t realize how much I needed to work through. I was in therapy when I found out I was pregnant. I stopped going because my first therapist was actually really horrible. Second therapist I got after the baby and she was great but I was so overwhelmed and still am - by the baby that I had to stop for a while . Maybe I can start back up one of these days . I still feel a lot intense emotions, anxiety, and anger / rage but it makes sense since everyone has failed me and not been there for me. I feel like strangers have been nicer to me than people I was close to. It’s so odd.
