@ssg - Your mind is a battlefield right now with competing thoughts at war. Trying to use logic to sort through all the thoughts, so you can determine which ones fit you and those that don't, end up creating foggy confusion. Instead of being bogged down in it all, try this:
You'll need a handheld-counter (Amazon has a selection of them at the link below). If you can't get one, the technique will work with pen and paper, the counter is just more convenient. Link Removed
You simply take note of every negative thought you have about/toward yourself and log it numerically. Don't write down or take note whatever the thoughts are, just count them and keep track of the total for each day.
This does 2 things: First, when you see how many negative thoughts/spoken words you have against yourself, you begin to realize the source of self-hate is coming for the most part from the negative thoughts. Your thoughts and words are powerful.
The second thing is that by counting you will have a measurable way to reduce those negative thoughts each day. When I first starting keeping count it was 80 - 90 negative thoughts or words against myself everyday. Those kinds of thoughts are powerful and induce/add to depression and anxiety.
The next thing to do is write down good things about yourself. Some of the replies you've received since joining this forum are a good source for you. Even a small list to keep in your pocket to look at frequently will help offset the negative thoughts. It does not matter if you don't believe the positive about yourself. Read them any way - think about them, say them out loud.
With time the positive power of truth will begin to flow into your mind and displace the negative as you reduce the negative thoughts about yourself.
One last thing here: Do you want evidence of your goodness? Here is one that comes to mind: The very fact you are so concerned about doing good is evidence the good in you is calling out to be heard. Listen to that voice...listen to the others on this site who have pointed out this very fact about your goodness. Displacing the negative is kind of like pouring clean clear water into a glass full of muddy water.
Pour enough clean in and the dirty is eventually gone. I know, this is how I survived suicidal depression, even though low level depression and anxiety are still present I live above them now instead of being submerged, suffocating.
I hope the link works.
