I was recently involved in a car accident that was my fault and I still feel shaken by the whole incident. How do I move forward?

Review the accident. See what took place and why

it happened. Then correct those issues and move on.

Chalk it up as an expensive LESSON----And comfort yourself in the fact that you will NEVER do what you did wrong AGAIN.---And be a safer driver for it.

Let your insurance protect you and repair all the damage. Start by talking with your agent. You bought the service. Now use it.

been there.it can have impact and make us feel shocked and nervous.however most simply set it aside as part of lifes problems we all encounter  sooner or later.  looks as though you have not got past the 'shock' stage. ideally we need move forward and stop recalling incident. being busy . drive with a friend for a while etc thus several trips with no further incidents will start to have us ease of the stress button.

You sit yourself down and do some research about how many people are involved in car accidents and what part of that number of MILLLIONS you are--and you put things into perspective. EVERYONE makes mistakes. You move forward by simply MOVING FORWARD.  You're getting obsessed--and if you keep this up, you could put yourself into a state where you'll need medication. 

Of course you're shaken. Of course you are guilty. But be a REALIST. Give it time, and it will fade. 

Just give it time.  The further it is in the past, the less it will bother you.

Acknowledge you screwed up, do not screwup the same way.

You suck it up and move forward. You made a mistake - accidents happen. 

Stay busy.  Exercise.  Get plenty of sleep.  Get in touch with friends.  Find a new hobby.  Learn a new skill.

Start slowly getting used to being in your car. Then try taking a taxi or an Uber, this will help you to feel relaxed in cars. Then ease back into driving on your own again.
