Let's see if this sticks

New here, but not to trying an app, program, joining a gym, getting a trainer, and so on...good news is I'm still trying and this will be my next new attempt. Have quite a bit to lose. I'm 49 and have never been so unhealthy in my life. This is by far the heaviest I've been. I'm scared I'll never be able to feel like myself again...but I will never stop trying. So let's go.
