I don't know how you feel but I know how I felt and it's no fun.
Keep your head up and don't try to solve the whole situation at once. Treat it like a pizza and cut it into manageable slices, then start at the small end. When you are overcome with grief your emotions are hyper-sensitive in both directions and small victories will feel good.
Step away if you have to-the Benz will wait.
Probably most importantly, grieve all you need to and know that it will get to a point where you know it's gonna be alright, you just don't know quite when. That's a good feeling. There are several stages of grief and we must pass through them all at some point. You can postpone or avoid but for true healing you must complete the cycle.
Be glad you had a good Dad and carry the positive with you. Also take comfort in knowing that many of us have been there and those that haven't probably will.
