Pee ocd - what to do?

I already read some posts about this and it seems to be incredibly common symptom. I have to pee multiple times before bed or before I try to leave the house, I need to get my bladder to feel completely empty or I end up feeling like I'm gonna pee myself even though I know logically it won't happen. So I go again and again until I'm satisfied and feeling empty enough. I often have to cancel my plans because I can't reach the completely empty feeling. I feel like I'm overly conscious about my bladder and how it feels. So now that I know it's a common ocd symptom I'd like to know how to deal with it? I've been suffering with this for years and I'm almost completely trapped in my home because of this. I can't afford therapy right now.
