Struggling with Undiagnosed Autism and PTSD

The past month or so has been tough. It’s finally become clear that my whole life of bipolar, insomnia, constant fear, irritability and a million other issues perfectly fits with Autism traits. I’ve had multiple informed people tell me this over the years but I never wrapped my head around it or did the research. It’s like my life makes sense now. My parents never paid attention to it even though thinking back I showed SOOOO many signs. They thought absolutely nothing could be wrong with me, so I got absolutely no accommodations and was taught that literally everything I struggled with was my own fault that I could “just choose to do better with.” I was pushed to the limit with mandated excellent grades, highest classes and achievements etc. I constantly expressed my sensory discomforts (primarily feeling absurdly hot and motion sick nearly every day) and they just thought it was a “preference” and often (and still do) not take me seriously. I have ADHD and they didn’t help even though my teachers told them. I’m just so upset with how I’ve been treated and resentful because I’m suffering now. I’m almost 25 now and have been masking around everyone my whole life. PTSD has only made it worse. I feel like absolutely no one understands me (and I think everyone’s annoyed with me 24/7.) The therapists I’ve been seeing just brush it off when i talk about spectrum. Thanks for listening….if anybody wants to chat about ASD I’m always here.
