Jump head first please

Every couple of months I do sth that I just can't believe I signed myself for. Today, is one such day. I signed myself up for sth way beyond my abilities and oh my GOD, am I freaking out. To this moment, hours after actively saying I am in, I feel like I am going to throw up.
Yalla, Rabena Yostor. PLEASE God, don't let me make a fool out of myself.

The good thing is I am not stressed about the hectic work assignment anymore, because I have sth else to stress myself about. Why I do these things to myself I don't have a clue.
