Wish I had done this sooner.

I recently started following this page, but I wish I had done it sooner. I started living alone eight months ago. Prior to that, I had a roommate, and we shared the apartment for almost eight years. She was more like my sister. When she moved out (May 2025), things got very weird. I was feeling very low and exhausted, and I just couldn't pinpoint what was happening. Initially, I thought I was just feeling alone and was ignoring every symptom my body was showing. Cut short to autumn, I was actually shivering when the temperature dropped to 12 degrees. It was unusual because I'm someone who goes to throw out the garbage without wearing a coat, even when it's -7. I didn't know what was happening and I was actually feeling very exhausted as months went. I didn't have energy, was frustrated all the time. I didn't know what the hell was wrong with me..until 4 days back several of my coworkers commented out that I look so pale these days and my dark eyes were getting much worse. Also I've been hearing from my friends that my hair was getting thinner as weeks went. I kinda ignored everything and was putting the blame on my Job stress. My manager asked me to take a break because he noticed that I've been getting really anxious and was losing my train of thoughts. I didn't even realize all these were happening because trust me people are envious of my memory. Ive such great memory..so I couldnt understand when my manager asked me to take a break. I decided enough is enough and went with a blood checkup. Out of all values, my ferritin was 7..I should have known this when my hair was shredding and when my anxiety rose. I just feel stupid that I didn't take any action for a year but rather putting all the blame on job.
