I am grateful you helped me understand your situation more fully. I had misunderstood your first post to mean you'd taken 15 years rather than 1.5 years off from work through the return to work program.
I completely relate to the feeling of shame related to being on disability. It's so unfortunate that society places this kind of feeling on those of us who are forced to the sidelines from our careers due to conditions we never chose. Migraine is a particularly tricky disease in this way due to its invisible nature. People are quick to judge and question us for being fakers - using a migraine attack to get out of a situation we don't want to have to partake in. As if it's a choice. In reality, I have found people with migraine to be the biggest fakers out there- but in the opposite way. Most people with migraine are faking wellness when they are very ill in order to try to participate in life's important events or to keep up with their work commitments: https://migraine.com/living-migraine/faking-wellness. It is a major head trip to receive this kind of judgment. And it can drive many of us to continue working (or return to work) when we are too ill to do so.
It sounds like you have a lot going on with looking into disability benefits through this current position while navigating a newish relationship with the doctor you mentioned. As I'm sure you know, having been through this before, the relationship we share with our doctor is key when it comes to pursuing benefits. Finding the right doctor is so important:https://migraine.com/living-migraine/evaluating-doctor-patient-relationship-right-fit. I'm confused by your statement that your migraine specialist isn't a doctor. Whatever the case, hopefully, that person can provide the support you need for benefit applications, medications, etc.
I'm assuming you've tried to work with your current job to make accommodations to the lighting (if at all possible) in your work area - and/or allow you to wear ear protection to block the noise. I'm not sure of your work environment and what is and is not possible. If unavoidable, leaving that position may be inevitable. Of course, that doesn't mean doing nothing. There are other positions (many work-from-home options) that allow you to control your environment.
Working can inspire a feeling of making an impact in the world and improve a sense of self-worth. That said, I have found that redefining the way I define my impact and self-worth is very helpful. Instead of focusing on how much or little I am dedicating to a job, I focus on how much and the way in which I love and care for my friends and family. Shifting my focus has helped me let go of the stress about not working in the traditional sense.
That said, the way migraine impacts our ability to work- and the invisible nature of the disease are demanding and difficult. You are not alone in this. It can help to come here and connect with others in the same situation. Glad you are with us. Keep in touch about how you decide to proceed. We are with you to talk things through.
