Anxiety when leaving home

Hey! Just wondering if anyone else has dealt with something similar. A bit of background: I have POTS and had a horrible flare up in March which led to us calling ambulances; I started on meds which didn’t agree with me; the POTS flare passed and left me with horrific anxiety on a level I’ve never experience before. I was still able to go out and do every day things like grocery shopping and see my nan but nothing more. Fast forward a few weeks my uncle dies and the grief and stress triggered a massive migraine, and bc I’ve never had a migraine before it scared me and I thought I was having a stroke or something. The migraine passed but my brain latched onto the fear of it and how it felt to have one. Long story short since the beginning of the year it’s been one thing after another. A few days ago I had the worst panic attack ever downstairs in my house (felt like I couldn’t feel my arm or face) and it sent me into a spiral. I am now terrified to leave the house in case I have a panic attack outdoors, it just feels so unsafe. I went to the shop with my dad yesterday and felt so bad, but i managed to do it and I was proud. Tried again to go to a different shop closer to home because I was already feeling bad, and it was horrific. I started having a panic attack, felt faint, my arm and face went tingly, so we went back home. I’m trying to challenge myself every day but I am really really struggling and not sure what to do at this point. I tried fluoxetine but had horrible side effects (which included a horrific dip in my mood) so I had to stop them. I’m seeing my doctor tomorrow to tell her everything and explain how difficult it is, but I’m just SO scared all the time. It’s like my body is constantly scanning for danger. It’s got to a point where it’s been going on for so long I’m just desperate to try anything to help me feel just a little bit better. I’m not asking for much, I just want to be able to go to the shop without feeling like I’m going to die. My question is has anyone else dealt with anything like this? The panic attacks are terrifying, and even though I know they’re “not dangerous” it does not help because they’re still so so scary and even worse when I’m out of my bedroom because if I’m by myself I can kinda lie down, do some breathing and talk myself round. I just don’t know how to get over this and I’m so so sad because I’m 31 and scared of being stuck like this forever 😭

okay so I’m 18, I’ve always been kinda a homebody , especially recently starting lexapro made my anxiety worse at first ect. I feel so scared to be in the “ real world” because I feel like I’m not independent at all:/ I’ve never had a job I had 1 at 16 for 2 weeks and it wasn’t to bad. I can drive , but it’s kinda hard for me , I get scared of thinking of the future and independence “what if I’m not capable” “What if my mental health doesn’t allow me too” ect ..:/

I’m new to this and trying to understand why I often feel stressed and overwhelmed by leaving the house to run an errand or see a friend. My boyfriend is an extrovert and I feel overwhelmed when I think of spending time with him because I know he wants to be out and about keeping busy. We live in NYC and lately the city is just too much for me - the noise, crowds, smells. I bailed on him today in a way I’m not proud of. He deserves to have a girlfriend that can and wants to keep up with him. I want to be that person, I want to WANT to do things. It’s so hard to know what is depression, what is personal preference, what is OCD, what is circumstantial, etc. I want to show up for my loved ones, I want to keep commitments, I want to get my errands done.
