Hi... Severe anxiety may cause these symptoms but is always wise to consult a doctor (psychiatrist/physician) to rule out any physiological cause (like, IBS, etc.).
Treatment of anxiety mainly consists of psychotherapy/counselling in most cases. Whereas medications can be used as and when absolutely necessary.
These symptoms of yours will go away within 15-20 sessions (weekly basis) of psychotherapy/counselling.
Next Steps
Consult a Psychologist.
CBT along with Lifestyle Changes and Interpersonal Guidance and Counselling is required.
