Why is this happening..?

Hi, I know I haven't written in a while, but I've been going through a lot of troubles. These include being stressed, having trouble sleeping, having an excessive amount of work, studying way too much, but still failing my test/quiz, and overall just feeling like dog sh☆t. I'm trying my best to stay happy for my beloved, loving, and caring boyfriend. He's been helping me with my mental health and work. I really need some recommendations to not harm myself in anyway. I really am trying to reach help from other and I felt like I needed to come out and talk about my inactiveness. I love you all so much <3!  ☆ ☆ ☆
