Experiencing anxiety. Or a psychologist!

I've been experiencing some anxiety for 3-4 months. I feel very nauseous, my heart rate increases and feel uncomfortable, this feeling is very overwhelming and I end up avoiding certain suituations. I don't know what has triggered this anxiety but I used to be a little anxious during exams or first day of school and very rarely when going to new places, I assumed that was normal. I got married 2 months ago, the preparations for the wedding were a little stressful and also my dog passes away 6 months ago, I was very close to him. I feel anxious mostly when I go out of my home and meet people whom I am not very comfortable with as a result I've been avoiding stepping out of my home. Sometimes I feel anxious even when I have to meet some close friends but the feeling goes away in a few minutes. I want to see a psychiatrist or a psychologist regarding this but it's a little difficult for me to go out of my house. Is talking on the phone or an online session possible?
