Canucklady,
Pandora is right... You are not going crazy. We have all been there.... Please don't think that you are. It may feel it, but in reality you aren't. PTSD is so ugly. It makes us feel so many awful things, yes including feeling crazy. It's only a feeling. It's not real.....
As far as the anger issue. Please just understand this.. Feeling anger is ok. We have ever right to feel angry. We have every right to feel rage, hatred, and every other emotion that comes along with what we have been through. It's just there there is a time to let it go, because it can cause more damage than good. Try and process your anger in a healthy way. Don't aim it at you. Like I said before what happened to you was HIS sickness, his issues, he was the control freak, and an abuser. It isn't you.
Try to do healthy things. Things that might bring a smile to your face,(even if only for a minute) go buy a good book, a plant, go to a movie, take a bubble bath, have a pedicure. Do something good for you....We all deserve a reward for what we have been through, what we are going through, and what we have achieved......
Be good to yourself, keep the focus on you. Your recovery, your achievements, your future.......You can do this....
Wendy
