Work life

I just started working at the plant my boyfriend used to work at. I unfortunately have to work the C shift and I am dying. It doesn't help that my job is just repetitive. I walk in a square my entire shift. My feet ache, my arms ache. This is a shitty job. It's only my second day and I already want to quit. My boyfriend is unfortunately gone for 3 weeks and my separation anxiety is through the roof. It makes me pretty upset and this job doesn't help in the sense that I am pretty much living in my head and he is all I can think about. I had to say bye to him today and broke down. He tried to reassure me that everything would be okay and he'll be back. 3 weeks is just a long time for me. I don't know how people who have military husbands and husbands who are away all the time do it. I've cried every time I am alone. And ugh he hasn't even left yet bhes leaving Wednesday morning. 😭
