I feel like I'm dying and no one cares?

I''m 23-years-old and have been told by 2 doctors (not my primary as I see him next Thursday) that I have anxiety. I will try to shorten the story. It started 2 years ago when I thought I had every disease from heart disease to a brain tumor. I think I had anxiety back then but never put a label on it. I feel in love and forgot all about my problems. This past November all my anxiety came back and I have not been the same since. I started having a burning sensation in my foot and immediately thought diabetes. I went to the doctor who told me that my shoes were probably causing this. I accepted the diagnosis because when I didn''t think about my foot, I didn''t feel the sensation. When I started thinking about it, I felt the sensation. In January I started having tingling in my right hand and went to the doctor who said because I have a job where I work on the computer all day it was carpal tunnel. She gave me an arm brace and the tingling went away. In February I was diagnosed with a urinary infection and again thought diabetes. The infection came and went. Out of nowhere then I started having mouth pain and headaches, so I started thinking brain tumor or stroke. Two weeks ago I had my first panic attack and after got really tired. I went to the doctor and he said it anxiety. I was still freaking out so I went to another doctor who told me he thought it was anxiety as well. This past Saturday I started having tingling in my hands and both my feet. Before it was just my left foot, now it''s both hands and both feet and sometimes the tingling seems like it''s going up my leg when I sit, I still have the mouth pain, I''m tired, etc. I went to a counselor today who said that he believes it''s anxiety with some depression as well. It seems like if I don''t think about the tingling it''s not there, that''s why it''s so weird, but I never stop thinking about it. The counselor told me to say to myself every hour, "I''m ok." I''m going to follow up with my counselor for a few weeks and he may refer me to a psychiatrist, but I''m also going to a 3rd doctor (my primary) next Thursday because I can''t believe it''s just anxiety. I can''t stop thinking I have something wrong with me and I feel like no one hears me. The tingling makes me think it has to be something else more serious. Has anyone had these anxiety symptoms? This is overtaking my life and I don''t want to do anything with anyone anymore. Thank You
