When will it pass?

My ex and I broke up a week and a half ago. I was still in love with her so it was really hard for me, still is. As both people around me and some people as suggested, I got a job. Yesterday was my first day and it went really good. I didn't think about her all day.

But today I feel like shit again. The moment I wake up there is this weight on my chest. The kind of weight that makes me not want to get out of bed. But when I don't get up I end up worse.

So I'm at work now, and all I can think about is her. The weight on my chest or the need to cry didn't go away today. And I can't keep myself from checking her socials. And every little change she does ends up giving me a mini heart attack and I walk anxiously all day. I can't bear that much anxiety.

Nights are a little bit better I don't think about her much. But the moment I wake up she flods my mind, because of that I end up not being able to get her off my mind. I'm going crazy, when will this pass?
