Feeling Unmotivated and Stressed About Money

I'm feeling really unmotivated right now. it's always hard to motivate but this feels like I can't even muster motivation to open a phone game. it feels like it would be worthless to play a game, like I wouldn't get anything out of it. I've been trying hard to get a better paying job and that's meant a lot of applications. I almost got one after doing like ten. I thought the interview went well but they told me they chose someone else the next day. I know I can get there but it's so frightening that I'll just end up having to quit this job like all the others. I just want to not be so worried about money. I want that to help me to focus on feeling better like if I could just buy the food I want to instead of penny pinching and never eating the right things often enough I'd be happier right? I just want to be somewhere stable so I could rest without feeling guilty like I'm sliding back into a pit that I'll never escape unless I give up everything that isn't essential. I'm afraid that'll just run my depression into the ground though. I know it's bad to never take a break but I know how tempting it is to let that break become my constant. I don't want to be stuck. I just want to see things actually get better. if I wasn't so stressed about money maybe I could get through some other hurdles. I could be confidant that I have something to fall back on.
