I’m new to this. Can’t eat at all.

Hey guys! I’ve been on this medicine for two weeks. I’ve gotten two shots so far. I’m on 2.5 mg. Today I was supposed to get my third shot, but I decided not to go and I will go in a couple days. The reason I’m reaching out to you guys here is because I don’t know what to do. I’m loving the fact that I’m losing weight. I lost 8 pounds in four days. My problem is I can’t eat. If I have a sandwich, I will have three bites and be completely done. The first week I was on it I was still able to decently eat. Now when I eat, sometimes I’ll keep the food in my mouth because I have a hard time swallowing. The other part to this is that because I’m having a hard time eating, I’m feeling really anxious and on edge. I’m a very bubbly, jokester personality type of girl. I’ve noticed after this past weekend, I’m a little more uptight. I know people are going to tell me that probably I should stop taking it. I respect and clearly understand the people who will comment and say that. But I’m looking for people to comment and tell me if this has ever happened to them. Have you ever had this hard of a time eating to the point where your body feels antsy? Also, I’m super thirsty. I’ve been drinking lots of water. Let me know what you think guys.
