I’ve been dissociating consecutively for 7 months. It got to the point where I paid $750 for an MRI of my brain to see what’s wrong with me in January. I was 100% sure that the MRI would show something medically/physically wrong with me. But the MRI was clear and my doctor couldn’t see anything wrong. I need help, I can’t live like this anymore, I can hardly have live conversation and I can’t focus on anything longer than 30 minutes without stopping what I was doing and staring at a wall. 
I have been diagnosed with BPD officially about 2 years ago and I take a medication called carbamazepine to help stabilize the mood disorder.
I have no interest in doing anything. I force myself to be productive but I can’t stay focused on what I’m fucking doing to stay productive! My brain constantly feels heavy and fuzzy. My memory is shit, I had a conversation the other day with a friend and he was  asking me to remind him when my birthday was and how old I will be. I paused and said I think I’m 23... which I am, but it took me a solid minute to figure out how old I was. I can’t think of anything besides laying in bed all day and sleeping/napping because that seems to be the only thing that makes the fuzzy brain feeling go away. I can’t even remember what I was doing the day before yesterday. 
I’ve become impulsive because of this to spike up an interest in something. I bought fucking roller skates so that it might help me go outside and do something. 
I feel like my body is here but my mind isn’t mine. It feels like I’m not here in the physical world. 
Please I’m begging for someone who has experienced this to validate that this feeling will end soon or some advice to help manage it. I can’t take this anymore.
