Where to start?

Hi everyone! I want to start on dbt and try do it myself. I may eventually go to a therapist but I can’t bring myself to right now. I recently went through a traumatic breakup w someone I almost got engaged to. The way I coped made me realise I may have bpd or something similar although of course I cannot self diagnose that.

But I thought I’d try dbt by myself for now. I tried marsh linehan’s book but felt it was hard to do by myself and didn’t feel very structured to me or a step-by-step.

Can someone please recommend resources?
