Welcome to the forum. Depression can be part of PTSD, or I guess I should say it is caused by it. Anthony said this in one of his articles.
How awful what was done to you is! But you deciding to make the best of your life and working toward that is the best decision you could make. Sharing your story here, receiving understanding from folks who have suffered similar things, is such a blessing for me. I hope it will be fore you too.
Here you can discuss how your abuse is effecting you and ask for advice from other sufferers about what they would do or what they have done in similar situations. It is amazing how many times folks here have done that for me.
For the best comic relief on the forum, search for a thread called You Know You Have PTSD When in the Chit Chat section. There you will find so much to identify with and laugh about too, which you cannot believe will happen when you read that thread, but it does! Then sharing your own quirky things will help us all too. Check it out.
