"Breakdown of community"
This can happen if you work remotely, or work in-office with a team that isn't collaborating effectively. If the work you do is isolating and you rarely collaborate with others, you may suffer burnout.
At our core we all want to feel like we're part of something bigger than ourselves. Being part of a team, even if it's as contrived as an office team is, can still be surprisingly important for ones mental health.
If you're feeling burned out consider if a lack of engagement with your peers could be a contributor.
That's my 0.02 at least.
Would be curious to hear if you found a way out, or a way to improve collaboration within a currently flawed group.
In general it's the responsibility of the manager to monitor the health of the team as a unit. If you have a manager it may be worth bringing this issue to their attention and working with them to find a solution. The manager has the authority, and should have the respect, to make the necessary changes to your team dynamics to improve collaboration. What this means for your team, depends entirely on what the source of the problem is.
For as much as managers get a bad rap in the tech community, they really do have an important job. Steering the ship and ensuring the wellbeing of the team is their number one priority. A good manager should be open to your comments and appreciate the opportunity to work with you to increase valuable collaboration.
If you don't have a manager then you may need to wear the manager hat. My recommendation in this case - not knowing you or your team - would be to identify the source of the collaboration breakdown, and then reach out to your colleagues to see if they feel the same way. Assuming everyone on your team is cordial, they should be open to a discussion on how to promote a collaborative environment. If your teammates are NOT cordial, well, you've got an entirely different problem on your hands...
In a previous job, I was nominally a member of a very strong and effective team, but the work I was assigned was isolated from the members of that team. I came to feel like I wasn't "really" on the team (there were some social factors that contributed to the feeling), and I got tired of nobody knowing or understanding what the hell I was doing. Open a pull request and everyone is all "wait, what is this? Why is this thing like this?". It sucks.
