Shoulder capsulolabral repair. Not regaining ROM

Sorry for my english in advance.
I am 24 years old and I had capsulolabral surgery 5 months ago. Except for the instability I had a pretty strong shoulder and the prognosis was very good. However, Didn't start physiotherapy until week 8, and didnt mobilise muy shoulder un external rotation until week 12. Public healthcare, I trusted they knew what they were doing, now I know I probably made one of the biggest mistakes of my entire life.
I am at 135 degrees of passive frontal elevation, 15 of external rotation, and 45 of internal rotation.
In the last months I have noticed no matter what I was not regaining movility. 2 times a week of physiotherapy and working very hard and constantly at home. I have regained 10 degrees of frontal elevation and 5 degrees of external rotation in the last two months.
The physios keep telling me I have to give It time, patience, but I dont trust then anymore. I think that if I continue at this rate. Im never going to regain at least a normal ROM, im not swimming anymore.
I dont know what to do anymore. I am starting to become depressed. Have an appointment with my trauma in one month
If anyone had a similar experience I would like to know how it turned out for you. Or if you know anything about it, what can or should I do from now on, I would really apreciate It.
Thank you.
