Worried and confused

Hi, I’ve been very tired and mostly unmotivated for a while now. Started from middle school and kind of carried on. It not consistent, sometimes I’ll get a random boost of energy and be able to be productive, but then it’ll get knocked right out of me when something inconvenient happens. I find I struggle taking care of myself, always too tired and not bothering to do anything until it gets kinda bad. I also keep forgetting things, and can’t really do a lot of stuff consistently everyday. And I get very frustrated with noises and movement from others, esp when I’m working. My parents are loud a lot, and I honestly can’t handle it. Started thinking and worrying a lot more too. I honestly don’t know what’s up with me, I’ve heard people suggest neurdivergency (Fidget a lot, picking, biting, sensitive to sound, absolutely hates tight clothing.. But im not sure), or maybe even depression. I don’t know too much about either so.. Any suggestions? Is this just an average thing? Am I looking too deep into it? I wish I can ask someone professionally but I doubt my parents will listen.
