After all you've been through and all the medication you are using, you are considering getting stoned because 'you feel like you're holding her back' ? Weed might well help you but is it really worth the risk? I'd say not. Weed is very unlikely to help with anxiety and will probably make it worse.
Be patient. Try getting a hobby, something you can really put some effort into, progress with and really flourish at. Setting goals and achieving them over a period of time can really help with a positive state of mind. Try eating a healthy diet and exercise 2-3 times a week.
This is exactly what I mean
