Social anxiety affecting my life

Thinking about booking a doctors appointment due to my anxiety, its consuming my life prevent me from doing a lot of things. Going to family events, appointments of any kind, sometimes work, new stores or places of any kind, dates with a person of interest, quiet waiting areas / rooms of any kind. It takes so much energy and it’s mentally draining, my stomach gets extremely upset ( severe nervous bowel moments )

Just wondering if I do make an appointment what would the next steps look like for treatment ? ( looking for insight with treatment )
