I bailed on something I was excited about, but I know progress isn’t linear

To get out of my comfort zone I went back in person for class, after being online. I’m also trying to find a part time in person job so I’m around people more (wfh job, luckily). And since I joined in person classes I get very nervous before, even crying. I decided to join a student organization- I got in! Well last week we had a meeting. I had very bad insomnia but I still pushed through. This week I began my condensed class (hybrid schedule so it’s my only online class). And since it is condensed I feel overwhelmed. Well Wednesday my student organization is doing something, and we aren’t exactly allowed more than 2 absences. I canceled on it. I was excited to go but I’m mentally so tired. I also struggle with shyness so I didn’t talk to anyone in my student organization. And I may just resign from it completely. I at least know I tried but I’m kind of disappointed in myself too.
