Should I depledge my sorority?

[freshmanxxroxxx2012]

I am currently in the process of pledging and I don't know what my life is anymore. I have no free time and am constantly freaking out. I have really bad anxiety that I was able to keep under control until this process started by going to the gym but now I can't make it to the gym due to my lack of free time. I am also taking 18 credits worth of science and am beginning to see my grades lower. I have started constantly involuntarily shaking due to all of the stress and my anxiety. I have also been getting a lot less sleep. I am about 3 weeks into pledging and would still have about 4-5 weeks left.
