My boyfriend has ADHD

Em

I need advice. I want to support my boyfriend through everything. He keeps frequently having random melt downs and is finding it difficult to interact with people recently. He’s been diagnosed with ADHD and I know it is effecting him quite a lot. I want to be there fore him and I want to learn more about it so if anyone knows anything can you please let me know? Even small things like helping him cope when he’s feeling depressed and making sure he’s getting help with school work when he struggles. I shouldn’t get to involved but does anyone have any advice I can use?
