Compromise with my therapist about not hiding in my bedroom anymore

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 8/6/2019 so havnt really left the house since. I basically hide in my room and just read books. I used to be very active socially and loved my career I worked hard to build so my therapist thought a she shed would count as “going outside”. It’s a change of scenery and I can people watch as my patio overlooks a park. I however am now severely disabled and 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 some independence back. A bit of normalcy or something close to it?. Just something to enjoy and look forward to. I want a space that’s just mine and still be safe but I can still feel the sun and wind. Read a book, listen to music, watch the ducks that return every year. Maybe put some flower pots?. Now at just turning 40 this is what count as my first big step. It seems a bit pathetic but it’s a purpose a goal to work towards for me. The shed in the pic is way bigger than the actual one I want to buy. I’m accounting for shipping, givealittle site fees, shed light and locks. The person/persons who hurts me knows who I am but I don’t know who they are and they were never caught so that’s why I don’t really leave the house.
