Right now you in a bit of a panic mode. Just breathe and know that its not all over. Advice given on here and what you'll read from DR and DB is not instinctive.
It seems like you are in a trance thinking that you are perfect together and she just can't see it. Maybe she did leave because of your depression. Whichever reason, she has convinced herself you are not good together and the marriage isn't worth saving. But instead of showing her positive attitude, you need to start showing positive change. She can talk to a lot of ppl who may be opposed to your relationship but ultimately she makes the decisions. Stop focusing on her friends and families opinions (I did this too and it got nowhere) and focus on yourself.
So you quit your job. Have you got a new one? She's talking about seeing the country and you think I want to do that. Go do it! When I speak to others about countries I traveled to alone they always say I wish I could do that. I can't phantom what is stopping them aside from possible limited financial budget. Some are just scared to do things alone.
It seems your wife has trouble with confrontation. Both times she left you a note and never directly spoke about her concerns with you. Texting her will not get you a response because aside from lacking confrontation skills she really does need space.
While she is making all these plans allow time to yourself to figure out what you want. Nettles is right, get a lawyer. You're not admitting defeat by getting one, but a desire to protect yourself in the worse situation. Its marital insurance. You're still in the early stages of being left, and I promise you it will get easier if you do something starting with yourself.
