I have a situational stutter as well and I find it difficult to get techniques to stick. I have this quirk where I don't stutter at all in therapy so I find it hard to learn things like fluency shaping. I try to find a bit of time each day to practice speaking. I usually record myself and present something. I will try to talk for 15 minutes on something I am working on or a topic of interest. If I don't have something I will read a book or article out loud. In this time I work on the pace of speech and try to integrate some of the techniques I have learnt. I have struggled to find a speech therapist that specialises in stammering. Instead I found a support group that consists of people who stutter. We call each other and have regular meet ups. I find these shared experiences and a group working towards a common cause is really helpful.
