Struggling with Social Pressure and Self-Improvement

I've taken a shower after four days , I feel less greasy but I still want to avoid contact . I've even been able to focus on myself for a while . I feel pressured whenever I'm around good friends of mine . I don't want hugs from them anymore , and my stims have become more heavy . I'll catch myself swaying and whistling more frequently . I think it's because I'm nervous about finals and summer school . I can't process that I'm trying to improve everything at the same time . It's like I'm coming back , but the end of the world wants me to start over .
