Is it weird to receive money after boyfriend dies?

A little over a month ago my boyfriend that I lived with for 3 years and was with for about 4 and a half, died unexpectedly due to a car accident. I have received so much love and support from my friends, family, and co-workers...it's really been overwhelming and wonderful at the same time. However, one thing that happened that I did not expect was that I received a VERY generous gift from my division at work, in the amount of about $250. It was just a card with a bunch of cash (obviously just had people give whatever they wanted to) and a nice note saying it was for me to use how I wish and to help with any financial situation this might have put me in. At first when I saw it I thought it was a donation to the charity that we had people donate to in lieu of flowers, but again thought it'd be strange that they would be giving me the cash like that instead of a just a note saying they donated...I had to read the note a few times to make sure it was for me. I again received another $100 from an individual employee that I am closer to and another $20 from someone else. One of the managers from one of the other programs also told me she had another card for me that her employees had put together. I am really touched by this but at the same time feel SO weird accepting it and have just never heard of such a thing. I am 25 years old and lived with him so I am sure they are not sure what type of situation this put me in financially, but they also know that I have the support of my parents (maybe just don't know if they can help me financially..but they can and have been). I told my friend at work that if anything is helping me right now it IS not having to worry about money and being able to treat myself, go out a lot with friends, take weekend trips, etc. So in a way I feel like their gift is going toward my well-being in that sense and I do plan on making a donation to the charity. But has anyone heard of such a practice?? I've never had anyone very close to me in my life die so I wasn't sure.
