Psych Ward for Agoraphobia?

I’d like to preface this by apologizing if this is a dumb post, I just genuinely need to seek another’s opinion on this matter.

I am 18f, and have suspected I have Agoraphobia for quite some time now. Brief summary, I dropped out of school at 14, have gone out maybe a total of 30 times the past 4-5 years. Lost all my friends, and barely speak to the family I live with.

My family has made no means to help me, and I have no idea how to help myself- besides doing whatever I can to make sure I keep myself alive (which ends up with me spending too much time online, or doing whatever I can to pretend this isn’t happening to me). But this has escalated to a point where I feel like I’m beginning to go insane, and I desperately need help.

I have tried therapy in the past but it has never worked on a deeper level. Everyday is the same miserable experience on repeat, and I don’t feel alive anymore.

So I guess what I’m asking is: Would it be possible to admit myself into a psych ward for something like this? Honestly I haven’t done much research on the topic, but from my naive perspective, psych wards have always seemed to be for those fairing much worse than me, and with worse conditions.
