Are you getting counseling? Sounds like you need to consider it. Medication is very helpful, but therapy is a much better solution long term because you will learn how to cope with the overwhelming feelings of anxiety. Anxiety makes you fear every little step in the future. You need to slow it down to what works today. You need to be realistic about what deserves terror. Tell yourself that instead of the worst case scenario, maybe the best will happen. What if everything works out fine?
I like the diagram that says, in essence:
Is there a problem?
If yes, can you do something about it?
If yes, then don’t worry.
If there is nothing you can do about it, then don’t worry.
Is there a problem?
If no, you don’t need to do anything. Don’t worry.
In other words, don’t worry. It’s in your hands to do something about your situation. It will be resolved, whatever decision you make. Tormenting yourself with worst case scenarios is not helpful.
