Can I do this again?

I've been struggling to keep up with my 90days home workout p90x3
I've done p90x five years ago and it gave me amazing results but then stupidly enough I stopped and I took these results for granted, I kept telling myself I'll go back but every time I do I talk myself out of it using some lame excuse
It's been five years now and my weight is even worse than before, I'm so angry as myself for letting myself go like this. But now I've started again with p90x3 its been only two days, it's so freaking hard but I will do my best. I really hope I can stick to it now.
This app seem cool
I've just installed it and I think it's gonna help me big time
I could use your help and support as well.
