welcome toesquasher! this is a good place to meet others who understand, so i hope you can find some support you are looking for.
i think it might be helpful if you brought up some of those concerns with your T. integration is a goal for some systems but not all, and that is a very important decision that you all should be a part of. everyone's concerns matter. if your T knew of Baby's concerns, maybe you could talk about them and feel more comfortable with whatever decision is made. would it be possible to bring up those concerns with your T?
i'm sorry to hear that you have to deal with those procedures. i think it is really good that you have been working on grounding techniques, because i think that will really be the most helpful to get through those really rough times. baby's feelings are valid, and dealing with difficult feelings isn't easy especially in stressful situations. has she learned about grounding as well as the others? triggers can bring on lots of difficult emotions, but dealing with those emotions doesn't have to mean that you deny the issue or the person having the issue... i think it just means taking in the stressor/trigger and identifying the solutions in a more constructive and healthy way to get through the dangerous situation/feelings. i wish you the best of luck, and keep working with your T on these issues... i think that therapy is a great resource, and pc here is a great resource too. again - welcome!
