Just be mindful that there might be different legal standings between emotional support/therapeutic pets and service dogs. Where i'm from, people with service dogs (whether they be psychiatric or for a physical disability) can stay in a property that wouldn't otherwise allow pets. Be sure to go to a proper association and get all the appropriate documents. These must be kept safe so as to provide evidence if necessary. Getting assigned a service dog can actually be a long and arduous process, the waiting lists are often frustrating and even then it can take time to get an suitable match. So i would only really advise looking into service dogs if you're absolutely sure. Pet insurance/vet bills may well be covered for you by the association but food can still be quite expensive, so there's financial considerations too. Pets generally are a huge responsibility so if you're unsure i would wait until your circumstances feel more appropriate. Good luck.
