Tips, tricks, help???

Hey mamas! I was just "officially" diagnosed today when I saw my regular psychiatrist. I've been absolutely drowning lately and my husband said I should bring ADHD up with my dr as a possibility. I'll be starting a low dose of Vyvanse to see if it helps. I just want to be a functional adult 😭 I have twin 12 year olds and a 2 year old and I feel like all I do is keep them alive. I have terrible organizational and time management skills so we're late for everything including school and the house is a mess, not so much dirty but it's my "organized chaos" all over the place but my husband better not dare touch my stuff (I'm sure iykyk). I spend hours upon hours on my phone doing nothing of importance and I feel like I'm absolutely useless. I'm a SAHM/on lifetime disability (chronic migraines, fibro, other things) but I don't feel very wifely since I don't do crap around the house and my husband enjoys doing all the cooking. Thanks for reading my rant. I just want to feel like a normal human with a life worth living.
