Hi Cands and welcome!
I too am sorry to hear of your brother's health, and also am hoping he has had a good recovery!
Returning anxiety is not unusual, and a trigger such as you were experiencing is understandable.
The good new is, that since you had such a nice reprieve from your challenges previously...you can do so again, and get back to that place of feeling good.
What do you think was the main contributing factor to your recovery last time?
Can you look into repeating that treatment...whether is was medication, therapy or self-help?
As hibee mentioned, we have great Resources here to get started (see link below)

...and see your doctor to discuss your options if you feel like you need more help beyond what you can do on your own.:)
Keep talking with us as well...support is key!
