When I was horseless, I had to focus on my other goals. Fortunately, I had three adorable "goals" (my daughters), who by their existence reminded me that they were my priority at that time.
I did stay involved in agriculture and horse-related issues as a volunteer, doing education and outreach on legislative issues and such. I also kept a few bits of tack that I could touch as something concrete (a crummy headstall with bit, a halter, and an extra leather curb strap!).
I sold my ranch saddle and gear first for the rent one month, and a year later sold my hunter tack and the rest to pay for a semester of tuition. Those were tough to do. The memories we can have attached to objects! I understand.
Best wishes at getting back into and around horses.
