This might sound silly, but I can't find the answer to my question anywhere. My whole entire life I have shown symptoms of anxiety, and got diagnosed with severe anxiety at 8 when I had my first panic attack. When I was 11 and started middle school I started to get depressed and got diagnosed with severe depression that same year after I started seeing a therapist. I'm 16 now and things have not really improved, I also got diagnosed with borderline personality disorder this year, along with tons of other medical issues (juvenile arthritis, scoliosis, asthma, alkalosis tetany, nose issues that affect my breathing). I have been seeing therapists, psychiatrists, and tons of other doctors continuously for almost 6 years with really no improvements. Also, I couldn't ask for better parents. They believe me, listen to me, support me, and will do whatever to help me (luckily money isn't an issue for us). So the thing is this, I have not really had any trauma in my life besides small things (if these even count) like minor bullying, friendships have never ended well for me, and minor sexual assault once. So why am I so "messed up"? Can it just happen for no reason, or is there something from my childhood I'm repressing? I appreciate any type of answer, thank you for reading :)

TDLR; Is it possible to be very mentally ill even if you have had a wonderful life (no type of large trauma)?
