Anxiety relapse

I came on this sub a couple weeks ago because I found myself experiencing anxiety symptoms again after being anxiety free for 3 years. I was on medication and recently decided I wanted to get off of it. When I did a traumatic situation occurred in my life that brought back my anxiety symptoms. I felt so lost and lonely, and most of all I felt disappointed in myself. I took 3 weeks off of work and school, and got back on my medication. I started going on walks everyday, even twice a day at times. Taking cold showers and taking supplements. It was really hard and didn’t provide relief at first but I kept at it. And after a while I felt a bit better, every day I felt a little bit better. Now my physical anxiety symptoms are gone! But I still feel weary and scared, I feel like I don’t trust myself. I don’t trust my mind. I’m scared to go back to work/school, what if the symptoms come back again? How can I slowly inch back in to my busy life without triggering my symptoms again?
