Shortness of Breath: Adderall Connection and Concerns

Hi there. I am asking this because I have consulted with my doctor before, and then got a second opinion with another doctor before and was told it was probably nothing due to me being so young. I was never given an answer to what is possibly going on. I started taking prescribed adderall in July 2020 for ADHD and started to experience shortness of breath about a year and a half ago. My blood pressure is never high, usually around 118/72 but my resting heart rate is usually in the 90s. The “shortness of breath” feeling is how I can describe this feeling of needing to constantly take a deep breath, and most of the time the deep breaths aren’t satisfying. I have to sometimes reposition myself and sit up straight or lean forward, etc to get a good adequate deep breath. But even when I get a good deep breath, it doesn’t satisfy me enough to stop the urge. The “short of breath” feeling pretty much persists all day, it just comes and goes. I assume it correlates with the adderall. I experimented before and stopped taking my adderall for two weeks, and the short of breath feeling stayed days after I stopped taking the adderall. It stayed over a week of me quitting the adderall, and that was a year ago when I first experienced the symptoms. So I don’t know if it’s related to the adderall, or if it’s something else. I do occasionally have heart palpitations with or without adderall, although they are harmless. I do not have palpitations during the shortness of breath episodes. I do suffer from bad seasonal allergies, but currently I haven’t been feeling any of the usual seasonal allergy symptoms so I don’t know if I’m even in season yet. I don’t know if this is allergy related but I’m on prescription allergy medicine (singulair) and it is still happening. So I was wondering if this is a cause for concern or not? Do you think this could be cardiac related, or potentially something else? My dad does have extensive cardiac history but I am young and am not worried. I just do not want to overlook any potential concerns just because of my age. I have tried asking my doctors but I don’t want to keep switching doctors and have them not take me seriously, or think I’m being a dramatic person. I just want a fair answer based on my symptoms instead of getting a “you’re young I’m sure your fine” answer.
