I wish I could permanently work from home

I have only been home for an hour and my anxiety has come down to a manageable level. Do not get me wrong it's pretty high but it's doable and I am not in full-blown panic mode like I've felt on edge all day. I have honestly considered stepping down because I truly believe my work stress has had a major impact on my mental health.

I feel like I've bitten off more than I can chew with this job and I leave work almost every day wondering if I fucked something up. I worked over 100 hours these past two weeks and I am dead exhausted. I just keep wondering when it will get a little easier because everyday ifs like I learn something new and have to remember a new policy.

I honestly think that working from home would be easier. I feel like id be better at my job if I didn't have to go into the office. I don't know why but I honestly feel like being around so many people lately and the stress of having to prove that I know what I'm doing. I don't think I'm making any sense it's just I'm struggling to be around people and I honestly do not know if I'm capable of doing this job.
