If you know or suspect you might be on the autism spectrum, you might want to consider social skills training from one of the many advocacy groups, such as Autism Speaks.
If you have issues regulating your emotions or behaviors during difficult day-to-day situations, you might want to consider one of the therapeutic modalities such as Cognitive Behavorial Therapy (CBT), Dialectical Behavior Therapy (DBT), or Acceptance and Commitment Therapy (ACT).
If none of these suggestions resonate with you, send more details. Good luck with building your new training regimen!
