I didn't real every comment - there are many. But here is my opinion: This is pretty common in the late 20's. Lots of changes, then suddenly, it is the same thing every day. I am about 10 years older, and my life has completely changed since then, part luck and part my own choices. My advice:
1. You aren't your job. Concentrate on something other than work. Have a truthful answer to "what do you do?" that isn't work. I'm an artist, but the pay is terrible, so I gotta make money other ways. What do you do?
2. But I understand the job has a big impact. Take an honest look. Do you actually hate the work? Is it tolerable? Stressful? Boring? Or are you simply coming to terms that your dreams that you worked towards haven't quite come? There isn't much to do about the last, but all the rest are fixable. You have a flexible degree, and you can use it in different industries. Schools, retail, and so on. If you are actually unhappy, see how far you can use that degree you have.
3. If you are in a relationship, decide if you are happy in it. If not, make changes. They don't have to be extreme changes. This might be more true if you've been in a relationship for many years, as both of you have probably changed since your early 20's.
4. If you are single or do not have children, start getting out of the house regularly. It is difficult, but worth it. This isn't bad advice with children, just harder, and possibly easier if you involve a child or children in this case.
5. If you have a weird thought that you might be depressed or anxious, get this checked. Or if this doesn't seem to lift after some time and action - or if action seems to be too much - get checked. It won't take care of your problems, but it will make it much more likely that you'll be able to take the action necessary to do them and get yourself un-stuck.
