Hi HunterG,
We all share in your loss...
A few thoughts stand out right off the bat. First, I congratulate you on being willing to open yourself up and reach out to others. Being open to that risk - because you're never sure how others will respond - reveals incredible strength and self-confidence on your part. And please take note how everyone above has responded - each has responded with great empathy. You should feel good about for taking that risk. And way to go to my fellow Westies!
Second, please take note of your initial question: "Other than reminiscing in memory how do you cope?" This might be seen as a subtle point; in my mind, it is a most significant one. Namely: When you stop asking "Why?" and start asking "How?" you have reached a significant transition point in your grieving. It means you have begun to accept the loss and are just struggling with how to incorporate it into your daily living. This signifies a major achievement on your part, and you should reward yourself for reaching it. It's hard, emotional, and draining work. You are on the right track and you should be very proud of that.
If there is anything else I can offer, it's the following... Always take the time to simply feel. It will hit you at the craziest of times, driving down the road, at the grocery store, at a gathering of friends. Instead of denying the feelings, let them take over. If it's an inconvenient time and place, simply excuse yourself and yield to the moment. Let it go... As much as it hurts, it will be rejuvenating. It may seem like you are taking two steps back for every step forward. It will get better over time...
I do not know if you are a spiritual person or not. Whether or not you ever have been doesn't even matter. The important thing is that the power of prayer or meditation or whatever suits you best is very powerful. Ultimately, God/Allah/Yahweh/Bhagwaan/Buddha doesn't care how you pray or meditate - just the attempt to do so will bring you a measure of peace. There is an inner sense of trust that comes from faith.
Lastly, if you have a friend that will simply listen in a non-judgmental way, one that can do so without telling you what to do, consider asking them if you could just talk. I believe this is one of the most valuable things a friend can offer another. A few years down the road, neither of you will ever remember what was said. You'll always know that this friend was there for you when you most needed it. It's one of the most incredible gifts any human being can give another.
I sincerely hope this helps. Hang in there. You're doing great!
