anxiety and health concerns

Hi there. I am 42 with a 30 yr history of anxiety. Im on Effexor 150 mg and Xanax .5mg as needed. ive been having some medical concerns lately which has increased my anxiety. for the past few months I have been very tired, depressed, brain fog (well this has been going on for years), my menstrual cycle has changed the past few years and have gotten heavier, ive also bee n very cold. so I was thinking pre-menopause. went to the dr and she ran bloodwork and ordered a thyroid u/s and a pelvic u/s as well as a sleep study. bloodwork came back normal. and I had the ultrasounds on Monday. today was my drs apt and I was having a lot of anxiety. I woke up this morning panicking and abut 30 min later my nose began to bleed. it was BAD. it bled for about 30 min and it was pouring out and down the back of my throat. but it finally stopped. I went to my drs apt and found out that thankfully my pelvic u/s was ok but my thyroid has 6 nodules - 5 they are not worried about but 1 is 1.8cm and they want me to see an endocrinologist and have it biopsied. I am worried but I have done research and heard it can be pretty treatable. but after my apt I still haven't calmed down. ive had a bad headache esp on the left side where my nose bled. that sideof my nose still hurts and my sinus on that side hurts too. im terrified of my nose bleeding again. I also don't know why it happened and if it could be something worse. my dr didn't seem that concerned about it though. I also have a hx of sinus issues and had sinus surgery 4 yrs ago. I originally went to an ENT in Jan because besides being tired I also had a lot of post nasal drip. I had a CT scan done and the ENT said my sinuses look great except for some mucus on my left side near my teeth so he felt it was more of a tooth problem. I also have had isseus with those upper molars. the back one I had a root canal on 10 yrs ago and the next one in ive had 2 root canals done. id decided just to have that tooth pulled but the dentist talked me into seeing an endodontist. I did and he took xrays and a 3d scan. the x-rays showed an infection around both teeth so he wanted to do a 3d scan so that he could see if we could salvage one tooth. I still haven't heard what the outcome of that scan was. now im panicking about the nosebleed on that side and thinking about sinus cancer but ive recently seen the ENT and had the CT so he would've seen that right? and then im thinking brain tumor and I think im just overthinking everything and I just cant calm down. I just wish Id never gotten that nosebleed today. if I hadn't have I would've felt so much better I think. I just feel tired and weak and shaky and out of it. anyway id appreciate it if someone could talk to me. thank you.

Thank you for your response. I really appreciate it. my mind is just going in all sorts of directions. I keep thinking that with the nosebleed now and with my sinuses and teeth problems and I get ear pain that its sinus cancer or a brain tumor. but I did just have a CT of my sinuses so I would think it would show something in my sinuses. im just going off the rails. I know. I think my mind is trying not to worry about the thyroid so Im now worrying about other things. I will check out the resources thanks.

thank you! I like that saying! I will remember to keep saying that to myself!
