Hi, long time
Sorry you feel this way. I think you should really try to engage, for yourself and for your baby too. Although its hard, talking will get easier once to build up a trusting relationship with EIP.
Also, I would take advantage of the help EIP are offering, because when you come to the end of the 3 years and move onto CMHT, they offer barely nothing. I've been with them for over a year, and never had a CPN, nor been offered therapy and my care co-ordinater is rubbish. However with the EIP team (assuming its the same team) had CBT, a CPN who came to see me at work, and was good and a support worker too.
Maybe write stuff down and show them. I do that sometimes, and its easier than talking.
take care xxxxx
