Obsessions and anxiety

So, on Monday I kept going back and forth to my maths teacher making him mark because I was so afraid of failing I felt like I needed reassurance. I didn't even realize but it was my OCD making me do this compulsive behaviour. I reflected on it and I feel like such an idiot for letting my anxiety get the better of me.
Today, I'm in careers class I felt like my head was foggy thinking was hard all my fears about what happened on Monday feeling like I embarrassed myself in maths class came to my head. I looked at my Fitbit my heart was 111bpms resting I knew my anxiety was reering it's ugly head. The fog was making it hard for me to do a chart for work days rooster for my computing class. I'm just telling myself it doesn't have to be perfect don't overthink it and I think that made me push a bit farther. I asked the teacher for help she explained it. I guess I still struggle to do things without reassurance and guidance. It makes me worry that if I'm like this at class. At home I don't do anything myself I have to be told things, it's like I'm so jumbled up and bundled inside I find it hard to think for myself and do things myself. It's just easier to sit in the chair all day and do nothing but be on my phone. I know I overthink myself to the point of anxiety that it disables me. I thought of making a schedule for myself and printing it. I think I will do that having an hour of study time. It would be good for me to do things for myself. And rooster in 20mins of chores. I'll start small and eventually I hope I'll be able to do my chores properly for longer. It would take a lot of pressure off my mum as she would have to do as much. I'm hoping that as I do more the anxiety will become less and I'll became confident and competent in my life. It's the little steps that can produce the big changes I need.
