Struggling with Agoraphobia: Seeking Advice

So I don't really know how to ask this but is there anything I can do for Agoraphobia without medication? I can't leave to go to the store without panicking, I can't even step out onto the front porch without running back in side. My doctor is trying to refer me to someone about the agoraphobia to actually fully see if it is that but he most definitely thinks it is. I stayed in my bed for two days straight without leaving the bed only to use the bathroom and even then I'd feel uncomfortable. I forced myself to get out of bed and try going down stairs by myself and I kinda succeed and I was happy. when it comes to stores I can't be around bright lights, lots of people or just people coming at me and I definitely can't be around loud noises without me wanting to back up into a shelf. I hate this I use to be able to go into stores and be more independent but now I can't, I get negative thoughts, thoughts about me dying and its causing depression now. I just need some advice or help something. 😔
