Something special for Valentine's Day

So my fiancé and I have been together for 3 years and friends for 5 years before we got together. My fiancé was hit by a car almost a year ago and we have had a very long and rough year recovering and as he is battling with depression and anxiety now as well. Our relationship has nearly ended a few times this past year as we tried to work through a few things. Now he is taking anti depressants and seeing a councellor. I want to do something really special this year for Valentine's Day. Is there any suggestions of something I can plan
