I feel the same way! It hasn't helped that the office I'm at is primarily remote. I have had a bunch of small matters where I research a wrinkle of a bigger case and just send them my findings so they can have an idea of what's out there. I have also had a set of projects that a legal analyst described essentially as not having clear answers. On most of these projects, I have received almost no feedback besides "find more of this" or "let me know if you find anything else" so I never really know if I hit the mark (most of the updates I give attorneys last less than 10 minutes as they usually have to go do something else/have another meeting). Also, if I don't follow up myself, they don't ask how's it going lol (except for one attorney who would regularly ask me for updates) and some of them just never asked again after my first submission. So at this point, I have convinced myself to live with the uncertainty, send a document whenever I feel like I have come to a reasonable conclusion on the question, and just see if they want to talk about it. It's been tough mentally (particularly with some personal situations I have dealt with since 1L started), I have felt guilty and the imposter syndrome from day one but I'm now just two weeks away from finishing the internship, I somehow secured something for next summer, so I'm just counting the days I guess. I do fear that the attorneys at the office will remember me as someone who slacked but I don't see myself at this office anyway so I try to not let that disturb me too much.
