Trying to get diagnosed with adhd
I've been trying to get diagnosed with adhd for a few months now. My therapist can't diagnose me and she was taking an inordinate amount of time to get us the resources or send me to someone so I went to my doctor. She luckily can diagnose ADHD! She said from what me and my dad described it seems likely that I do have it, and gave me questionnaires for two teachers to fill out. I gave them to two teachers that I think I interact with most, and when they were returned they were mostly ones and zeros.
I desperately need to know how much these will affect my chances of a diagnosis. I think the forms are incredibly useless personally, because most of the questions are things that I would have to have talked to my teachers about, and I try to hide any failings I have as much as possible. One teacher even basically outright lied. Possibly not, because it was on a question asking about the quality of my assignment completion and he said above average (objectively untrue, I have turned in like half the assignments and all were late) but I go to an alternate school so maybe that is truly above average there, or he just likes me (I used to do a lot better).
I'm really desperate to try medication, because in the place I am now I will not be able to go to college. There isn't really an argument there. I've tried all the non medication things to help, but they only help a little bit and usually stop working after a few times or depending on my mental state otherwise. My mental health in general is also suffering right now so I don't even have the motivation to try sometimes (it's way better than it used to be, but still not at all good).
Could I have somehow gaslight myself into thinking I have adhd?? I score very high on the self assessment but maybe it's something else? I can't find anything else that matches all my symptoms from online research. Sorry if this makes no sense, I'm probably kind of spiraling right now due to a lot of other shitty things going on in my life.
