Need advice on wedding planning and postpone

Engaged 7/2021, wedding scheduled for 2/2022. Already have a venue booked. I have had an anxiety disorder most of my life and due to recent medication changes that felt necessary (because I don’t think those meds were working) everything became worse. Crippling anxiety and fear on a daily basis, working with a doc and seeing a counselor weekly. A month ago I planned to go dress shopping this upcoming weekend and although excited there is no way to tell if I will be able to function due to anxiety/panic attacks. I want to postpone everything honestly so I can really focus on getting better. FH is not happy about this and I have people coming in from out of town for dress shopping with me. I could maybe grin and bear it through dress shopping if I’m having anxiety, although ideally these events are joyous. Although planning a wedding is stressful I don’t feel stressed about that exactly. It is more physical symptoms of anxiety and panic that interrupt my day and life. I am even on disability from work due to this issue. Im wondering fellow bride’s thoughts/feelings on this topic - anyone experience similar things? Thanks in advance!
