Hi there,
Holy smokes, it sounds like you and I are going through the exact same thing right now. Hugs to you. You pretty much described how I feel as well. I wouldn't say that I'm unhealthily attached to my t or anything, but during hard weeks (like the last few) I really just can't wait for my appointment. I feel like I just need to keep talking about as it builds up every day. I think what I've learned this far (not to say I like it) is the goal is really just to learn to tolerate feeling this way while were in the process of working through all of this heavy ****. Exactly what you said about "sitting with the feelings." I know it can be super hard to function, anything but being in bed can seem to hard for me. I think sometimes we kinda just have to be okay with that as long as it's not ruining our lives or going on for a really extensive period of time.
Obviously not a professional opinion, but just what I'm feeling about the same situation.
Good luck.
