I suggest you try to limit your conversations to 10 minutes. More frequent 10 minute conversations is much better than just a few 20 minute or longer conversations. There is nothing wrong with needing to keep conversations shorter. If you keep each conversation shorter, you should be able to have many more in a day.

Plus, consider the content of your conversations. Many longer conversations start getting into stressful issues. Abstract issues also tend to create cognitive load/stress. If you spend most of the time listening, that can be a much more stressful conversation. It takes a special person to listen to long winded people. You can not afford to be a dumping point for others so guard yourself from those types of conversations.

There are basically three different conversation topics. people, things, ideas. Talking about people tends to be the most stressful.

Dogs can be very good for anxiety if you find the right dog and it does not create living stresses regarding feeding, picking up messes, barking, etc.

We had an assistance dog consultant at our brain injury support group last winter. There are good programs to help if you have one in your area. You likely would just need help selecting the proper breed/temperament. I doubt you would need a dog that has been highly trained like some do. Basically, a good companion dog.

SSRI withdrawal symptoms can last for months. It can help to replace the SSRI with 5-HTP and maybe L-Theanine to support your likely need for serotonin. 5-HTP is cheap and easy to find. Worth a try.

My best to you.
