Hey Paris - I think the quicker that one embraces their feelings, the quicker one passes through them. Atleast that's what I've heard - I'm working on practicing that on a day to day basis - When I feel something I don't want to feel and find myself stuff it I almost intentionally try to bring it back up. Maybe spend a day just grieving, writing, crying, watching sad movies and just get that stuff out. I know journaling helps me a lot.
I've definitely used exercise in the past but it's hard to exercise when the feelings keep coming up. When my fiance broke up last year for 2 weeks, I got drunk that night and after that I didn't eat much. Used it as an excuse to diet essentially, and then we got back together... Just saying this because I know advice is easier said than done.
SUPER hugs and bottom line is BE GENTLE WITH YOURSELF
