<human>: Can you provide a brief rundown of the text in within 3 sentences?

I was dating a girl for 5 years that I probably would have married. Last year, I was diagnosed with AML (acute myeloid leukemia), which was sudden because I was previously a healthy, _very_ fit guy. After I got sick, she had left me because she said she couldn't handle not knowing if I was going to live or die because of the AML, and that she had to look out for her own well-being.

I've since recovered from being sick, and am about to go back to work in a few months. I am currently a high school teacher for a public board in Ontario, but am feeling inadequate with what I can contribute to a future relationship. Because I come with the baggage of having had AML, I feel like I can compensate for that by having a more prestigious job, with a better salary. 

I have prospects at a financial firm (it's owned by my cousin) where I would be making substantially more than I currently am. Perhaps if I were to make a career change, It'd be easier for a SO to be proud of me. I'm torn as to what I should do? 

The irony is that I've worked very hard to get a permanent tenure as a teacher (which is next to impossible right now in Ontario), and had to work extremely hard to overcome leukemia (constantly working out through chemo, etc.). But I think people look at having had it as a stain, which is why I'm torn.
<bot>: Ex-gf left me because I was sick, now I'm unsure if I should get a better job to make up for having been sick for a future girlfriend.
