(Please folks, I have a great respect for therapists, as well as other secular forms of help. There are many wonderful aspects to people and organizations even if they are completely opposed to the church. This comment is not to the contrary of any form of help. Nor is it prescribing any beliefs or ethics upon anyone.)
OP - the Eastern Orthodox Church is a mystical religious organization who claims to have preserved the true teachings of Christ. Do not throw the first stone. Do not judge lest you be judged. Love your neighbour. Many people of all faiths aspire to live this way. I would say the Eastern Orthodox Church is a reliable place to find people who take the teachings seriously.
There is a great love for monasticism in orthodoxy. One famous monastery in Arizona St Anthony's. There is an idea "Every home is a monastery". We celebrate monks regularly during services and many people visit monasteries regularly.
I recently joined this church not having been raised in any church. After many attempts of trying to identify what's missing in my life - relationship, school, work, drugs - I reached a point of total desperation, and then after reading lots of spiritual books I found the orthodox church.
I'm very sorry to hear of your struggles. I hope you can find some help or meaning in this horrible time. I normally would not share this info because in 99% cases it makes things worse. You are asking for radical options and mentioned becoming a monk, so this time I'll bite.
If I may attempt to be encouraging for you in this difficult time. It's a sign of strength to be exploring radical options. To me it means you won't settle for a common trope that you know won't help. Not bending to common sense can get you in trouble sometimes, but I believe it's also the only way to the real truth.
