That's what I was paying the therapist for- to help me. Yet she didn't
Assume by therapist you mean psychologist? How did she not help? By not collecting your daughter from in-laws and delivering her to you to solve the issue? By not ringing the relevant Social Services in your State for you and acting on your behalf to solve the issue? None of this is within the remit of their job. Thats not help they can give you.
It would be like me going to a psychologist because I’m upset my cars broken down and I can’t afford to get it fixed and do not know where to get it fixed, so I’m walking everywhere, being late to everything and I’m stressed. Their job is not to tell me where to get funds from, or to Google or ring around car repairers to organise to get my car fixed, or indeed to show me how to Google this. Their only job is to determine why my mind is so muddled that I can’t manage this myself. To see if I’m presenting with something to be diagnosed and/or strategies I can implement to be able to function adequately. And privately, they would likely think to themselves it’s a good thing I don’t have a drivable car while I’m in such a state.
As you continually refuse to accept, there was nothing stopping you from contacting your relevant social services. Their contact details are public, it would have taken a two second Google. Or, how about a lawyer? You say no one helped you, that’s literally their job in this situation (while it is not a therapist/psychologists job). You paid a psychologist seemingly, you had the wherewithal to look up a psychologist, contact them, make a booking, turn up and pay them as you say. So there was nothing stopping you doing exactly the same with a family lawyer for a one off consultation for them to give you the advice and help you needed if you were truly so utterly clueless.
Not bothering to engage with anyone at the time, when all information required to do so was publicly available, is completely on you. It’s not on your parents, it’s not on your in-laws, it’s not on your therapist, it’s not on social services, it’s not on the court. As everyone keeps telling you Social Services MUST have been involved, it’s impossible they were not. They needed to make an independent assessment for the court. You must have either been assessed, or refused to engage with them, or they could not locate you? But then at one point you say you were assessed by a court appointed psychologist which would have been via social services. They obviously felt, at the time, that your child continuing to live with your in-laws was best for your child. If they thought providing g you with supports would have ‘fixed it’ they would have noted and explored that, however they obviously assessed this as not feasible and a court agreed.
