No Mary, you are not crazy. This is pretty normal for most who are in our situation. My Jim has been gone over 6 years, Sept 2, 2008, and I still have bad days. I too have lost several friends and relatives recently. A very good friend died this summer and then on his birthday, my mom passed way and a few days later another good friend and on & on it goes. This was in September and it really hit me hard. I basically am doing OK, but some days are much harder than others. I don't think the feelings ever really go away, we just learn better how to deal with things.
I haven't had any counseling or meds either, but I am fortunate that I have a very close friend who's husband passed away 3 months after Jim and out situations are so much a like that we know, understand and can talk things through with each other. I also have a group of friends we have known for years as couples and now all the husbands have passed away. Jim was actually the last one. I keep in touch with them and we get together once a month for lunch. This site, and those friends are what get me through those hard times.
Keeping busy does help and I think you could use someone who you can talk to honestly about your feelings who truly gets it. Unfortunately, unless they are in the same situation, they really don't get it. Most just think we are doing fine. They haven't a clue.
Vent all you want or need to Mary you are not being stupid. Just expressing how you feel. It does help. Come here and share your feelings when you need to. That's what we are all here for. To help and support each other in any way that we can.
Yes, this too shall pass, but you never know what or when it will hit you again. Take care Mary. Hoping you can find ways to work through these feelings.
Love & Hugs,
