I have a tendency to really worry about my T. I have no concrete reason to (nothing has ever indicated that there is a problem). It's just that because she is so important to me, especially seeing I lack intimate relationships and she is my main source of emotional support, that I am very afraid of losing her. I've invested so much in this, and it really feels like it's the only thing I have to cling to at the moment. Unfortunately the fear is so pervasive that it makes it difficult to fully trust in and benefit from the relationship and all the positive things I get from it.
I've experienced this before with people I have been very close to. I tend to attach very powerfully and then fixate on one person. They become everything. And then obviously there's the great danger of losing that person. I think there are a few reasons that this is a particularly powerful dynamic for me: the (fairly sudden) death of my father in childhood, my mom being unable to be there for me emotionally due to her alcoholism, another attachment figure having a lot of personal problems come up in her life that led me to feel emotionally abandoned (and extremely guilty) because she couldn't be there for me anymore in the way I craved. So it seems I've developed a negativity bias where I assume everyone I love will be taken from me.
I have talked about this with T, but I'm still not really sure how best to deal with these feelings. The reality is that I have no control over what happens. Bad things can happen at any time. Often they don't, but how can I trust? How can I give in to the attachment fully knowing how damaging it would be if it were suddenly cut off? If anyone has any insight into this I would truly appreciate it.
