Need to focus on me!

Hey everyone!
I just downloaded MFP pal after a 2 year hiatus. I'm trying to better myself and make life the best it can be. I am determined to lose 50+ pounds.
To be honest, I have been struggling with depression and not leaving my house for long periods of time. Anyone who can relate knows how hard some days can be, especially if no one knows how you're truly feeling. But I want to change and I want to be around like-minded people. No one can do this alone!
I'm open to food advice, workout tips, etc.
