I mask all day at work and then snap at my family — why?

Yes, this is a very common pattern clinicians see, especially in adults with ADHD. It does not mean you lack patience or that your family is the problem. It usually means you are spending most of your regulatory capacity at work. Masking takes real energy. At work you are monitoring tone, managing attention, suppressing impulses, staying organized, and meeting expectations, often without accommodations. For an ADHD nervous system, that level of self control is exhausting. You may look calm and competent on the outside while burning through cognitive and emotional reserves internally. When you get home, the structure drops and your nervous system finally exits performance mode. What comes out is not intentional irritability. It is depletion. The brain no longer has enough capacity to filter, pause, or regulate emotions, so small stressors feel overwhelming and reactions come faster than you want them to. This is not a character issue. It is a bandwidth issue. Breaking the cycle usually means addressing the transition, not blaming the reaction. Planned decompression time before engaging with family helps. Lowering expectations right after work matters. Naming what is happening can reduce shame for everyone. Sharing the load at home where possible is protective, not indulgent. Longer term, reducing how much masking you do during the day is key. That may mean accommodations, treatment for ADHD, more external structure, or adjusting workload and pacing. You are not snapping because you do not care. You are snapping because you are running on empty. With the right supports, this pattern is very changeable.
