Anthony, how can we pick ourselves up and help ourselves if we are all we have?
This is the easy part... its called choice. The hard part is implementing it.
I have no support of friends or family. It is more than difficult to rely on only me for support when I am still trying to learn skills to get through each day.
You don't need support of friends and family to heal trauma and learn new coping skills. Its nice... but its not needed. In most cases, in your worst times, you usually find out just who your friends are who truly stick by you, and who aren't. Then you must also look at how much fault you have in those relationships breaking down, ie. if you break down daily, constantly depressed, etc... you must also review how much another can put up with before they must also take care of themselves and remove themself from the situation before they to get dragged down to depression, etc. There is a limit on how painful anyone can be before support around them says, "enough".
People recover by themselves every single day from trauma... you are no different...
Right now this forum and my T is all I have. I am on a downward spiral, I know that. I just don't know how to change it.
You are recognising many things, which means you are self evaluating, which is good. So, if you recognise you're on a downward spiral, then you recognise specific causes to it, you recognise emotions you feel, etc... write things down, read over them, pull your own life apart, put it out here on the forum and ask others specific questions to help yourself find the answers you need. More heads are better than one when it comes to problem solving... which is the power of online communities. You identify specifics vs. writing a novel, you ask specific questions via threads, looking for specific answers... then you review those answers and begin seeing what works for you, what doesn't, maybe even taking bits and pieces and mixing it up for you personally to create a new variant, that you find best.
Regardless how you improve, you demonstrated you have the skills to analyse the negatives, so now identify them all as much as possible right now, start looking at positives, then implement change. As more negatives arise, repeat process... Fear is a negative, and also requires exposure based treatment.
