Overly anxious dog

I adopted a 6yr old small mixed dog, she’s about 20 pounds, in July. She had anxiety,

but by the time I went back to work in September we had bonded. We would go on short walks, she did her business outside but she was getting nervous and the walks became shorter until now she will not go outside.

Now she runs from me in the house and will hide under the bed or in her crate. But she jumps up on the bed and sleeps with me at night.

I have tried everything to help her overcome the fear. The vet gave her meds but that seemed to make the fear worse.

The vet told me to hire a behavior specialist, but I can’t afford that. Does anyone have any advice? Has anyone ever experienced this before? Help!
