It sounds like you are dealing with quite a bit physically and emotionally, and it is completely valid to feel concerned.
The symptoms you mentioned, like feeling dizzy or blacking out after physical exertion, palpitations, shivering, faster heartbeat, fatigue, and disturbed sleep, can have many possible causes. Sometimes, these could be due to something physical like a
vitamin deficiency,
thyroid imbalance, low iron levels, or even something related to your heart or lungs. So the first step would be to consult a physician. Getting a few basic blood tests and a full checkup can help rule out anything medical.
If everything comes back normal medically, then it might be worth considering if stress or anxiety is playing a role. Anxiety can sometimes show up in very physical ways like this. In that case, talking to a psychologist can really help. Therapy can give you the support and tools to manage the anxiety and understand what might be triggering it.
What you are feeling is real and valid, and both medical care and mental health support can work together to help you feel better. Take it one step at a time, and do not hesitate to reach out for help.
