Good while it lasted

It was working well for the time I had it but it won’t open anymore and it’s not letting me get access to my entries or letting me write anymore. Please fix this

It exactly what I wanted

This app is basically a Cognitive behavioural therapy (CBT) worksheet. It’s easy to use and I can do it daily before I start my day. I always feel better after filling out the worksheet and I see how distorted my feelings can be after I’ve filled it out. I highly recommend it to anyone struggling with anxiety, depression or just general stress.
