Struggling with ADHD and Depression

I have adhd and depression among other issues and it makes executive functioning very difficult at times. I’m getting older and executive functioning is sorta becoming a requirement. It’s so hard and exhausting to exist…and I don’t think I can on my own. I know people find solutions and also I’m tired of looking. I can see myself working really hard and recovering/learning to manage all my things. But the road to that place is long and hard and I’m already so tired. I’m tired and I have so many resources and people supporting me. What will happen when they leave or die? I’m not sure what I’m looking for by sharing, but I want to share. I shared these feeling with my therapist and psychiatrist and parents and they’re trying to help. but i feel like i’m just going downhill. i’m not doing better. am I better than i was five years ago? than yesterday? some days i doubt i am. is there even a path to better or is it all made up. is it just downhill from here?
