Mental health Compromise with my therapist about not hiding in my bedroom anymore after SA

It’s embarrassing for me even ask for help as I’m usually the one helping everyone else but I dont have any other way. I was attacked & SA’d 8/6/2019 & havnt really left the house since. Extreme PTSD. I hide in my room & just read books. I used to be very active socially & loved my career I worked hard to build so my therapist thought a she shed would count as “going outside”. For now. It’s a change of scenery & I can people watch as my patio overlooks a park. Ease my way to seeing people in person. I however am now severely disabled & use a walker so working again to save enough fund is unrealistic. I tried with plastic tarps but they ripped off in high winds. My service dog recently died of cancer of the spleen so I’m just sitting in bed day in, day out, alone. I want to get a bit of normalcy or something close to it? something to enjoy & look forward to. A reason to get out of bed. I want a space that’s just mine & still be safe but I can still feel the sun and wind. Read a book, watch the ducks that return every year. Maybe the next step say hi to one of my neighbours? Wave to someone in the park? Who knows. Now at have just turning 40 this is what count as my pathetic first big step compared to everyone else asking for donations for but it’s a purpose a goal to work towards for me & my mental health. The shed in the pic is way bigger than the actual one I want to buy. I’m accounting for shipping, givealittle fees. I don’t know who hurt me so that’s why I don’t leave.
