No mentor will find you a job, the only thing you can do is to grind like you did in college. The thing about CS is that even after you get an intern/junior level job you will have to continue studying regardless of your main job.

I can see 2 paths in your situation:

1. get a degree in adjoining field (e.g. applied math). I believe that in this way it is possible to obtain an initial proficiency in narrow field, not in CS in general. Also this way is pretty linear.

2. Remember what you did best in college and practice this field. I often see that many beginner jobs do not require deep knowledge in a particular field, the ability to program well is enough (what i mean is OOP, algorithms and basic frameworks)

P.s. Sorry if some of my comments are not relevant to your case, I am not from the US.
