Just stepping out of my house makes me feel anxious because I've been sick for months and havent gone out. I remember going out a month or two ago and I'm not sure what is the true reason, but i started feeling queasy, bloated, I was panting, my heart raced. I felt that i had to go home IMMEDIATELY. It could due to pneumonia, or anxiety.

So.. I'm going out with a friend tomorrow. We will be taking a long bus ride  to reach our destination and the thought of it already makes me feel queasy. The fact that i always had motion sickness during bus/car rides is not helping my anxiety. I'm feeling dizzy typing this even. 

I really want to go and have fun. But i worry that my stamina is going to leave me panting and feeling sick because I've been on my bed all day for months.

I worry that i will get an anxiety attack and have to run home, ruining the day.

I worry that my motion sickness is going to ruin the day too.

Should i just back out?
