I once couldn't leave my house for almost 2 years.I had to get back out in the world in baby steps.First I walked out to my mailbox,kept doing that until I was ok with it,then stepped out by the road,kept going a little bit further as I could.Eventually I made it to a store,eventually went inside,eventually bought a couple of things,etc.

I had to just keep trying and keep pushing myself until I was finally able to do it.A little bit more each time.

It didn't instantly get better,it took a couple of years of continuously trying.I still sometimes start feeling the old feelings,but I just force myself anyway.I think it's a PTSD thing,it's hard to go out sometimes when I have been triggered.Doing soooo much better with it now though compared to when I couldn't leave the house at all.
