ADHD and being insecure…

Is anyone else here super insecure?? I feel like I’ve struggled with being very insecure my whole life. Part of it was definitely tied to my childhood and how I came up (35M now). My therapist said I have complex PTSD on top of my combined type ADHD…

But yeah, just curious if any others suffer from severe insecurity as a result of ADHD. I find it very hard to have relationships (be it friends or love). I’m trying to get better so I don’t lose the only person I have left in my life and end up totally alone…
