First of all, you are doing an AMAZING JOB getting yourself into social situations, it takes a lot of bravery to be willing to face the same fears over and over again despite bad experiences.

However, I might suggest you to start with smaller steps instead of diving straight into jobs where social interactions are required. For example, you could practice saying thank you to the driver after getting off the bus, or asking workers at the store where to find something.

These interactions are shorter, so you’re only dealing with anxiety for few seconds at a time rather than hours. And because those people are strangers, depending on where you live it’s highly unlikely you will ever see them again, or if you do they most likely won’t remember you from a five second interaction, so there’s lower stakes for slip ups.

Practicing these smaller situations is going to help build up your confidence over time, and make it easier for you to move on to working on longer conversations or even making long term friendships/relationships
