I am going through the same thing right now. Be easy on yourself. One minute I feel strong and hopeful about the future, then the next minute I feel sad that 25 years is coming to an end. I am trying to take it one day at a time, keep it in the moment if I have to. It is my grieving time and it is normal after a breakup from someone I have been with for so long.
Here are a few things I do:
Get a message
Hot Bubble Baths
Exercise
Read a good book
Oh and MUSIC MUSIC MUSIC
I am really finding out that listening to certain songs is helping me more than I ever thought.
Hang and there and keep posting! This site is a total lifesaver in situations like ours. The people here really understand.
