Hi Bonnie,
I totally understand the frustration! CTP is built for going at your own pace. One step at a time. My phone won't allow me to put many dapps on it either. Not enough space on the internal storage and can't put them out to the sd card which would have space for them. It's okay for me I like working on my laptop better anyway. But that is just my preference. Anyway, don't stress yourself out. You're learning new skills and it takes time.
