My going away party

Tomorrow I am going to be having a "open house" style going away party and I'm feeling pretty nervous. My parents are going to be saying a few words and I am going to have to walk around and talk to people. I just hate small talk soooooooooo much. My anxiety is going up just thinking about this. I'm going to have to be fake around people for the 100th time. The only reason I'm really doing this going away party is to officially say goodbye to everyone and to get gifts that can support my college tuition financially. In other words, I do it for the cash. I know that shouldn't be my motivation but in the midst of my depression it's the only thing I can rely on. So wish me luck. Comment down below if you have any tips on how to get through this.
