My seperation anxiety from my boyfriend has caused him to leave a job and be let go of from one in the past. He took off work for a few months a little over a year ago, but as my anxiety began to get better, we agreed he should start working again so he started a new job where he works 4-5 days a week and comes home between 2:30-3pm. It made me anxious at first but I very quickly got used to the routine and comfortable with it. I’m no longer met with anxiety when he’s at work, just bordum.
 However we got into a big argument a few months ago when he was drinking and speaking his mind, and he told me that he wants to be doing more with his life, working full time instead of part time and maybe going to school. It was a real wake up call for me and i’ve been 100% supportive of him ever since. I didn’t have an anxiety disorder when we first started dating, he didn’t sign up for this and it hasn’t been fair for him. He’s done everything in his power to support me these past few years and he deserves the whole world in return.
He was recently offered a job where he will be working 5 days in a row, coming home at 5pm. Not at all what i’m used to, and the idea of our routine suddenly changing and him coming home later terrifies me but I encouraged him to take it. He starts in 4 days and i’m trying not to let it get to me but it’s 1am and sure enough the waterworks have come out. My biggest fear is ruining another job opportunity for him. I think my brain gets confused and is convinced that I am still that girl from a year and a half ago who was having daily anxiety attacks and couldn’t be alone for an hour. I’ve grown so much since then and have come so far, so i’d like to think that I will be able to handle this and i’ll quickly get used to it like I got used to his current job.

What are some things I can do to calm my mind? What are some things I can do for his first week of work to distract myself and pass the time?

Overall i’d like to start working, because if i’m at work it’s going to make the day go by much quicker and make me even more independent from him. But I don’t have a car at the moment and i’m still not quite at the point where I feel comfortable enough to work, so in the meantime I could use some help for how to get through the current situation. Thank you in advance ):
