Me and my T are going through the same process.
It's called transference - the pain of what others have done is transferred onto your therapist, making you believe they are likely to respond the same way
OR
It's projection - you believe the way you see yourself is the way your T sees you
Neither is generally accurate. However both are perfectly normal.
I've been in therapy just over 3 months and the last month or so we've really been looking at this. I have BPD (Borderline Personality Disorder) so my fear of losing someone I care about is so immense, it is like the grief of them dying if they do go. I will avoid that at all costs.
I believed (like Albatross - and I'm not saying they're wrong) that I could do therapy in a detached state. Maybe it works for some, maybe it doesn't. For me, it didn't. Why? Because long-term therapy is basically a time of re-parenting. That's why therapists are often looked on as pseudo parents - they fill that role. I needed that since my own mother was so messed up that she allowed her 15yr old daughter (me) to be removed from her care while the man raping her daughter (not a family member) was allowed to stay - because he needed to be "brought to the Kingdom" (aka made a Christian). I need a lot of reassurance, validation, care, commitment, acceptance and approval and when it is in my best interests and healthy for my T to do that, she does. Eventually, like parenting, this increases the client's confidence in session so that they can start applying the insightful therapeutic revelations in a real world context. Gradually, practising and persevering builds confidence to the point where the client is empowered enough not to need the therapist anymore - which is EXACTLY what a parent does (or should do)
They give you what's called Unconditional Positive Regard (UPR). If you do not feel cared for, you either have issues to work through (not being able to see when someone truly cares for you) or you have the wrong therapist. Either way - the only real way of handling this is being brave enough to tell your therapist how you feel. You'll be able to see from that how they respond. If they are dismissive or play games (asking "why does it matter to you if I care?" "What makes you think I don't?"or "OF COURSE I care, don't be silly!" words to that effect) - time to look for a new therapist. If they start behaving in ways which encourage your trust and actively work on showing you they care then it's you, not them. A good therapist knows trust is earned and with their more damaged clients, it will take longer. They might not go "you know I care about you" because care is something that is FELT not heard. If you don't feel it, then no amount of verbal reassurance will work. Instead they will begin SHOWING you they know who you are, SHOWING you they care. He/she will be expecting this and actually respect you for having the balls to admit to it - that's how mine responded... "that's a really hard thing to admit to, isn't it?" (AKA I know that was hard for you to confess that you're afraid of becoming too attached then losing me and I think you're very brave for doing so. My opinion of you has gone up, not down) so don't feel silly
I had an unfair advantage since my T made it clear to me (at the very beginning) that with BPD she was anticipating I would have trust issues with her. She said "With BPD if one week I cannot see you, you may experience that as abandonment" (guess what? The first and only week she's not been able to see me, my BPD hit badly!) I don't know about non-borderlines but for a Borderline it can take anything up to a year (sometimes more) to really get over the ambivalence and be able to trust fully. So I wouldn't beat yourself up too much - it's totally natural even for non-borderlines to have trust issues.
You have been badly hurt but you are still here, you are brave and strong and a fighter. An awkward conversation will feel awful but I can reassure you that on the other side it is a wonderful feeling knowing I can say to my T "I'm really struggling to trust you this week - I'm sorry". It helps, it REALLY does.
Good luck xxx
