Has anyone successfully put together a DIY SE program?

I'm not opposed at all to therapists, groups, online courses, or anything else we want to throw in that pile.

I simply can't find (yet?) a solution in my area for SE, and from reading and watching instructional videos that SE would really benefit me.

If we are analogous to houses, I haven't found a contractor yet, so I'm considering doing the majority of the work myself, and maybe hiring out a few subs.
