Unfortunately that is one of the major issues that may occur even if you no longer are depressed - being more comfortable with a state of mind connected with negative aspects, as in your case, death. An important thing you should take note of is that your emotions are still adapting to your life now and that it is a fairly unconscious process, so even though you may not feel that anything has changed, there has definately been a great progress. And referring to the question about your sanity; there really is not enough data to make any conclusions but it seems that you are over-analyzing your situation. In most cases the best thing you can do is to take a deep breath and evalute if you are blowing things out of proportion and start questioning your reality with all the variables available in the given situation. If you truly are worried I advice you to contact a psychologist, and do not be hesitant about it, they are here to help you so please do not be shunned by the unfortunate taboo views on therapists that our society has established. To me you seem fine, just give it a lot of time, taking your life will not accomplish anything. I wish you the best luck in the future.
