Hi Mattie,
I am approaching my 4 year mark now, and I can say those feelings never really go away. Some days I feel like I'm in an alternate reality, and that he really isn't dead. All I can say is just focus on your healing process, and keep close to your friends and family (the ones who are positive and good for you, negative people can only make your grief worse). I was also married to my husband for a short time, 3 months and 1 week. It wasn't enough time, and I don't think there is ever enough time with the people you love. The only advice I can offer from my own grief process is don't let yourself be consumed by fear or guilt. There is nothing wrong with continuing to live and enjoy life. Just try to think of what you would want for your husband if you had died, and live your life that way. When it comes time for your wedding anniversary do something really special that would both would have loved! I always go to our favorite restaurant and visit him at his grave. This year I can't but I will still do something on that day, and its makes me feel like I am still showing him I love him. I am even remarried now (boy was falling in love again a surprise) and I still celebrate and honor him. I even wear two wedding rings! Just do you, celebrate life and the memories, and give yourself forgiveness!!
