Doubt around finding a new high paying job in time

I have a job that ends in a few months for the summer. Right now, the job doesn’t cover all of my expenses so I’m concerned that I will have to keep using my savings. I don’t want to run out of this money. My thought is: “well, just get a higher paying job.” But the next thought is “I don’t know what that could be…and where that could be.” I also have a hard time believing I can make enough from one job. So my mind thinks maybe two jobs, but I don’t have the energy for that.

I know these are all thoughts. I have run models on this again and again trying new thoughts in a more positive direction but I keep coming back to these thoughts. Especially in times of fear and lack. I’m really looking for new thoughts that will stick. Any help to turn these thoughts around would be much appreciated. Thank you.
