How Can Severe Anxiety Be Treated?

Hi, Good Morning. I am a very anxious person and that help me in some part of my work however it also is a great deal of challenges in other situations, I do meditation daily early morning and before bed for 20 mins for the past one year. I have gained significant benefit from that. however I have a lot of occasions when i feel anxious very fast and take time to recover from the moment. It impact my discussion or presentation. On personal front I at times find it difficult to sleep and have been taking medication for blood pressure (which seems to be in control) My BP started last year when i fell ill with chicken gunia, had severe impact on my health and immune system. I seek your guidance on what i should do to improve my control on anxiety and other health aspects. Regards Mahendra
