Need to vent

I’ve been doing so good with dealing with my anxiety but some days all my negative thoughts rush into my head and i feel like all the progress I’ve made are gone. Like I have to start over again and again. I’ve had a very anxious but good day bc I ran errands by myself n now I’m just anxious mess again. I’m just so tired and worn out abt the anxiety of doing shit by myself. Can’t even go to the store by myself without anxiety following. My fiancé is very understanding and we go everywhere together, but I need to be more comfortable doing stuff on my own. Just sucks man. Im so tired of it, it just makes me feel like crying. I do SO good one minute, and the next it’s like my mind is a war zone. I’ve managed to slow down how much I overthink but I can’t stop it! I end up always feeling so drained by the time I get from home or whatever that it takes so much mental strength to clean or do shit. My fiancé works way more than me so I hate complaining about it. I know he would never judge me though. Ya girl just needs a break from my head 😭
