How much is too much?

Yes, it's too much.   People often have to find the right job and their niche but four in a year doesn't look good, but do what you need to do.  

But I think you need to get a handle on your stress management and depression or it's going to be a cycle that doesn't end.  

There is no perfect job.

Good luck.

I believe as the song says, "searchin' every which away" until we find our niche.

It totally agree with this.  I had several jobs over my lifetime in nursing and sometimes regret my choices.  The caveat of the op was "I suffer from depression, shut down and need to quit" which might be clouding the search.

Is having 4 different jobs in one year too many? I suffer from depression, and if a job gets too overwhelming, I shut down and become depressed and need to quit. It's happening again, and I'm qondering if leaving my 4th job in just over 1 year is too much? I just haven't found my niche yet. Please be kind.

Don't quit. Unless there is something scary wrong with the job, don't quit. I can sympathize with the difficulties of adjusting to a new job, but you have to give yourself time to acclimate. If you don't, each new role will overwhelm you and you won't get the chance to become comfortable with it, keeping you stuck in this cycle for even longer.

Stick it out for a few more months at least, and be patient with yourself in and out of work. I think it's pretty normal to be tired and even a little blue at the beginning of a new job, and if you have clinical depression that just adds to it. Don't expect yourself to be at your best just yet, try to sprinkle some calm and enjoyment in your days off, and just know that slowly and steadily, work will almost certainly get easier. Hang in there!

Definitely could use some counseling to sort yourself out. Find out what you want or expect, then research like crazy, but don't peg yourself down to one idea.

I think it is a mistake for everyone to talk about their "dream jobs". Reality seldom lives up to a dream, and dreams can turn into nightmares. I always looked for a job that would help widen my knowledge; you can't go into a new job and expect it to be 'perfect', because I don't think any job is perfect. And at the beginning you have to learn a lot of things you didn't expect, which is sometimes hard on one's ego.

Wishing you the best FOR YOU.
