I've been having this tightness in my chest and feeling really tired, plus I'm not sleeping well at all. It's also making my mood all over the place and I'm dealing with some shortness of breath too. Could these symptoms be connected? Should I be concerned or is this something that will pass on its own?

You may be experiencing symptoms of anxiety or stress. To help with these symptoms, you can try taking over-the-counter medication such as lorazepam (Ativan) 1mg as needed for anxiety. Additionally, practicing relaxation techniques, such as deep breathing exercises or meditation, may also be beneficial. If symptoms persist, it is important to consult with a healthcare professional for further evaluation and management.
