AITA for quitting my job 1 month in??

Not gonna lie here, I (28 F) was let go from my dream job 3 months in about 5 months ago. It destroyed me and took a long time for me to understand it was not me and get a little of my self esteem back. I did a course for business intelligence (while I was unemployed) because it interested me and wanted to stir into that direction moving forward.

DISCLAIMER: I am married to my (29 M) husband who makes 4 times what I make and has been incredibly supportive during this time. He himself wanted me to focus on myself and regroup so I can move forward. He can carry all the expenses for both of us by himself without any trouble. We also have an emergency fund.

Back to the main story… I did this course and started looking for jobs so I can go back to the workforce and pull my weight (I don’t wanna be a stay at home wife). It has been SO HARD to get a job and I start to get discouraged when I stumble upon this opportunity as a planning assistant. I have a little experience in this area and Im interested so I apply and thankfully get the job. I was so happy and excited to finally build my career but everything went down the drain on my first day. When I tell you everything felt off from the start is not an understatement. Mind you, I took the job even when it was a reeeally long commute because I thought it would be great and it wouldn’t matter. To put it lightly, besides the bad working conditions (which were not discussed with me prior to), the awful management system and the fact that my, now boss, didn’t clarify the area I was gonna work in; I found myself hating the job I took to a level that from the first week I was coming home with tears in my eyes and so much frustration that it messed up my sleep.

I thought about applying to other jobs while working there to get out of there ASAP but after 2 weeks of applying I became so stressed and depressed. I hated this job and I couldn’t get out. Not now that my family and friends were so happy to see me back on my feet. Of course, my husband knows everything, he’s my best friend and the only one I could talk to about it. He became so worried about my mental health that he proposed that I quit and he could take care of me like before, until I found another job but, I was so ashamed to be so weak that I needed to quit before I found another job, and then it hit me… It took me 4 months to get this job… when I pictured myself going through this for 3 more months I started crying. Eventually I agreed and I put my notice in the 3rd week of me working there.

I really didn’t want to put all the burden on him again because I know it’s selfish and my, now boss, had a conversation with me to let me know that it looks bad that I quit so early when the company has invested do much in me. I know companies only think of their interests but still Im not sure if I did the right thing.

AITA?
