Hi and welcome! I am sure that there are some great threads that you can read; you may want to check out the relevant sections for depression issues and I think it's called "Chicks in Control". You may find some relevant material that you connect with there.
Sometimes when I am looking for motivation I like to go to the mini-goals photo album forum. In contrast to the goal forum, in these threads people typically post throughout their journey. It can be more motivating when I'm in a rut or struggling to go look and remind myself how much of a difference losing that next 10, 15, or 20 pounds will make in how I look and feel. Then looking at the journey in those small chunks can seem a little more manageable.
I hope you find something that helps! Stick around and jump in on threads, everyone here is lovely and ready to support each other to achieve a healthy lifestyle.
