Anxiety Support Group
Anxiety is a physical condition marked by intense and persistent feelings of distress, fear, angst or dread. General anxiety caused by routine day-to-day stresses usually passes quickly and is experienced by almost everyone at one time or another. However, such feelings that linger over time and are very difficult to cope with, and which lack a clear cause, may indicate...

Get with a good therapist if you don't already one. They will show you tools that will help you live with the anxiety.
In my own anxiety management, I am forever seeking a balance between taking on so much that I am continually stressed out and taking on so little that I have time to over-think everything. It be a tricky balance and nobody else seems to have the inside data to know where the ideal balance lives.
Achieving that balance is an inside job. Nobody can do it for me, but I sure feel allot more confident of my balance when I am able to run the imbalances through my peer support network. The very network you just posted on.
Listening. . . What's in your balance?
Do you see a therapist at all? I would encourage you to do so as they are better equipped to answer your questions. I don’t know you so I can’t say with any amount of certainty what you can handle and when you need to bow back
It is good to be productive. Filling all of your time with activities that require obligations such as deadlines and times can easily add to the stress.
I too have anxiety, and I love being busy. Expectations are always high and I take on too much. The important thing is to recognize it and when you do, decide what is important. It is helpful to speak to a professional when indecisive. I have built the habit of giving myself at least 3-10 minutes each day to meditate. In addition to therapy, this is my "me" time when I can stop and just unwind, even if for a short while. And as for activities, I do some things that I can do in my own time without deadlines to avoid the guilt of not fulfilling the obligation, such as painting.
Stopping every now and then helps you gain some perspective and clarity and can help you find the answers you need.
Finding some balance is a constant work in progress. Best of luck, you will find it!
One of the things with anxiety is when you jumble everything together in a single paragraph, thus overloading everything because there's no space to "relax" , "unwind", "pause", and just be in the moment.
Best wishes as you find your way through all this.
