I have adhd and some other conditions but rn that's only relevant because I am on 40mg Medikinet ER and sertraline 50mg.

The next bit is just kinda a rant so if you wanna skip that, summary is I took 280mg of medikinet today and 50mg of sertraline. I had my normal morning dose at like 8 with 40mg and 50mg then like 7hrs ago I took 4 more adhd meds and then 2 more like 10 mins ago (total 280mg medkinet?) I couldn't find any info online so I just wanted to ask if its bad and if I should just sleep it off or smth? Main problem is today I had a big wakeup call about myself and how me being in denial about still struggling a lot with my eating disorder and also my constant need to get sicker, has been affecting the people I care about. If it was anyone else I'd immediately see that me constant complaining about feeling like ass and fainting and whatever to my friends while never making an effort to get better would have been so exhausting. Why did it take me so long to realise that my friends must have been so exhausted by me because what could they do for me when all I can do is complain about things that I've caused myself and it will never get better until I make an effort to actually get better rather than being scared of recovery. I should have never constantly complained to them about myself because realistically I know I won't get better because I'm too scared to truly admit that most of my problems with my health is because of my own actions. I can't keep blaming my eating disorder and my other illnesses when I don't make an effort to recover because realistically I can't keep making excuses for myself when I know all I have to do is get help because without professional support there will always be the constant thought in my head telling me to get sicker. All this really hit me like a brick and I was so upset and overwhelmed that I ended up taking 4 more of my ADHD meds like 7hrs ago (bringing me up to 200mg) and then another 2 like 10 mins ago after I hadn't really felt much. I think the total is like 280mg of medikinet (methylphenidate) and I didn't have any more setraline so I only had the one in the morning as my normal meds. I don't know why I did this but I didn't want to seem like an attention seeker by mentioning it to anyone so I just wanted some advice since I couldn't find anything online, what would this dose do to me?
