Starting to feel like I'm spinning plates

So my life finally seems to be getting some traction. I have the job services at the county building, new depression meds, a diagnosis for ADHD and the promise of medication for that starting next month, regular exercise and meditation, been reading healthier, made some therapy breakthroughs, and I've started to make some new friends. All this is ramping up, and I feel myself starting to panic. After doing so little for so long, can I really do this?

One constant in my life that I start to feel like I'm juggling, or spinning plates, and I have to exert a tremendous effort to keep it all from crashing down. Eventually I run out of stamina and it does come crashing down. I don't want to repeat this pattern. I want my life to be manageable. I'm hoping that once I start treating the ADHD this feeling will fade. But I have no guarantee. I'm scared. I need medication and I need tools. I'm broke, but I need a book I think.

I'm also worried about the social thing because I have no money. I've been punting, but this is quickly going to become a problem. I need a solution for this. I should talk to my brother. :(
