Could Reduced Appetite, Nausea Post Food Intake And Panic Attacks Indicate Anxiety?

Hi. Over the past couple months, my appetite has changed drastically. I used to always be hungry and could always eat. Since roughly around February, I ve noticed that my stomach will be growling but I won t want to eat or have an appetite or desire to eat because nothing sounds good. I have basically been forcing myself to eat and when I do I end up feeling nauseous for a few hours usually. I have had a harder time falling asleep, I have lately been going to bed around 3-3:30am. The other night I was up until roughly 6 am. I have been very stressed and overwhelmed and my mother thinks all of this is cause by stress from school, however I have been like this since early February. I will get very hot and start sweating, while my body itself feels cold or if the room I am in is cold. I will feel almost numb or funny overall, I have been just feeling not happy for a while as well. Also, I have been worrying and stressing over everything, and within the past going on three weeks now, I have had 3-4 panic attacks and 2 anxiety attacks. I will start shaking at random times or feeling very shaky even if I am not shaking. I have also had a lot of tension in the muscles in my back and shoulders. I have been trying to figure out for a while now if I could have anxiety, but I just haven t been sure. My boyfriend who got diagnosed with anxiety at the beginning of the year thinks I do, as these were a lot of the same symptoms he had.I just can t eat and I don t feel like myself anymore. I feel like I m going crazy and have no control over myself. Anyways, before I go to my mother or my doctor about this, I was wondering what you think this could be caused by or if I do have anxiety. Given that school has been out for almost 3 weeks and these symptoms have continued as well as some of my panic attacks and anxiety attacks, I would like to know if you think I have anxiety. Thank you.
