I'm depressed.

I got my first job recently so I'm exhausted all the time. Worked 20 hours in 4 days. And the utter exhaustion makes it easier for my depression to come out. I just spent the day with my boyfriend and we had a lot of fun but in the end I was depressed and I feel like I ruined the entire day we spent together. I didn't want to let him go to bed because I was crying. I feel so selfish. I was making him feel bad because he was trying to make me happy but I'm exhausted and it didn't work. I just feel hopeless. 😔
