Oftentimes we think the disordered ex needs therapy yet what about ourselves? When we're feeling down, we can use some cheering up too, right? That's one of the benefits of peer support. We've "been there, experienced that". We can commiserate and point other in positive directions.
So, while we in peer support are helpful, the fact is we are remote and to a certain extent anonymous too. Another fact is that so many of our trusted friends and family are clueless about the depth of hurt we've experienced from a hurtful, perhaps even abusive, ex.
That's where seeking out an experienced counselor is so very beneficial. Yes, we are not mentally imbalanced to the extent of being disordered, but all of us can use a helping hand now and then.

Sometimes we see therapy and counseling being mentioned interchangeably here. Probably it doesn't matter in peer support scenarios. Me? I typically use the term "counselor" when referring to the aid we seek when times are tough, though when speaking of the persons with serious disorders (Borderline, Narcissism, Antisocial, etc) I generally use the term "therapist".
My point is that we all can benefit from counseling as needed. Please do seek out local in-person counseling services. If at first you don't find a good match, keep trying.
Keep seeking the positives. You will never regret it.
