almost 6 months

It has been almost 6 months since my son died of suicide and some days it is better than others.  We had our group session last night and that always help for a while.  Have a problem, do you think I should get my daughter-in-law something for valentines?  We are close and I talk to her every day but we wonder if it will bring up too many memories.  We are going to have our two grandkids over Sunday night so their mom can work on Monday.  We love to have them.
