ugh anxiety

I am officially 6 weeks. I'm going to be honest I'm petrified. This is my first pregnancy and it has not been the best. It's weird my fiancé and I have been trying for almost a year I just didn't think it was going to happen then one day I randomly took a test and here we are. I found out at 4 weeks and three days. Ever since then my anxiety has been disabling. I can't focus, I don't leave my house. I'm really scared rather than happy :( I've talked to so many nurses and they all say it's normal. I've dealt with extreme nausea, headaches, being overtired and nonstop crying the first week into my fifth week of being pregnant. I'm tired of hearing that this is normal to be honest. I don't want these feelings to be "normal" because to me it's not. I have felt so sick and so down that I haven't even had a chance to feel happy. I'm praying to god, to make me feel better and happy. This is all I've wanted and dreamed of. I cannot wait to be out of this first trimester and hoping the second will be easier on me. If you have any good tips or advice to help me somehow switch my negative feelings to positive please share. I'm desperate. I'm scared even more now that I'm six weeks and have read so many posts about people being so sick. 😞 there has to be some good rather than being sick.
