I have been isolated for too long I think

I think Ive taken it too far I have gone outside maybe 5 times including moving house twice in the last 2 years I have spent my entire adult life with next to no human interaction and I finally have the opportunity to get a support worker come and visit a few times a week but she quit her job because of me and now I'm back to almost no human interaction and everyone who tries to replace her just makes me upset I can't keep living like this but anything that helps makes me so unbelievably uncomfortable and angry I've been told I'll get better since I was 12 and I've tried and tried but its always 1 step forward 2 steps back now I'm so isolated and alone I'm not even the lonely type
