Glad to hear things are moving in the right direction!
If I might offer up a few points, based on personal experience with similar thoracic/pressing issues:
When I really made progress earlier this year, it was when I laid off of pressing entirely for 3 full months. During that time I did scapular exercises of some sort - either for mobility or stability - for about 20-30 mins 5-6 days a week.
In other words, I went pretty intense on it and kept at it. I just say this because above you had mentioned doing face pulls "once a week", and that you gave it up and went to a PT after just a month.
I'm not trying to knock you, but I wanted to point out that these things require quite a lot of attention. I mean, your squat doesn't usually go up dramatically after a few weeks. Rather it takes months. Same applies to resetting your thoracic area.
Ok, I'm done preaching.
I'll recommend Inside/Out to you. It really covers a lot - including the pec stretching, etc. - and certainly costs less than multiple PT visits.
