Why are my stitches coming undone?

Ive been backstitching whilst using my sewing machine and the thread is coming undone with the slightest amount of pulling. Its extremely frustrating since ive been backstitching every time i do about 10 stitches and its still coming undone. What im i doing wrong?

can you take a picture of the item in question? It's will help us give you a definite answer as opposed to a guess.

you have to load it to a hosting site of some kind, like flickr or similar, then you can link it/ paste it here.

Two more questions that may not be immediately obvious from a photo but might help diagnose:
What type of fabric is it? How much stretch does it have (if any)?
What stitch settings and thread type are you using?

quick notes

if your using one of those handheld deals (ie handy stitch)
those are horrible and ive never heard of one working

if you got any other machine, it may seem like "duh"
but sometimes people tend to forget to use the bobbin (bottom thread)

The fabric im using is a lightweight cotton, im using the tight zig zag stitch and the tension level is 3. Do i maybe need to increase the tension level via the dial? Perhaps i should tie the end of the stitch together too? Maybe that could help since i havent done that

no, if the threads pull out something other than tension is wrong.

Maybe your bobbin isn't set into the machine properly. My previous machine (top loading) would create loose stitches like what you describe if the bobbin was accidentally set in upside down, or even if there was only a few inches of thread left on it.

I think my bobbin is set in properly as the little hook thing is pointing towards top in that little groove thing, sorry idk the name and also it makes a click noise when i put it in. I only leave a little amount not even an inch hanging out of the bobbin case. Am i supposed to leave a trail out that is a few inches long? Also would you recommend tieing the ends after finishing a seam or stitch? And maybe increasing the tension, i have it set to 3

Yeah, leave more trailing out of the bobbin, at least a few inches.
And no, you do not ever have to manually tie threads when using a sewing machine.
As for tension, it differs depending on your machine and what you're sewing, so I can't really say. In my own admittedly limited experience, problems that seem like they're caused by tension are usually caused by something else anyway, I'd eliminate other probable causes before messing with the tension dial.
Is there any way you can provide a picture of your machine, threaded and ready for fabric? We might be able to see what's wrong.

We need to see the stitches themselves also.

Now, if you lived in my city, there;s a class at a local shop right now on how to use your machine. Look around in your area, it sounds like you need some in person instruction.

It's hard to tell what's going on in the pictures of the fabric itself, but are you trying to join two pieces with the cut edges directly against each other while zig-zag stitching across both pieces, rather than folding the two pieces so they're flat against each other and stitching a seam ~1/2" in that goes through both pieces?

If so, that's the problem. The stitches themselves are probably fine, but it looks like (again, hard to tell because it's blurry -- do you have a macro mode on your camera?) the fabric itself is fraying at the edges and that's what's causing your stitches to pull out. Is the thread staying with the fabric, but the seams are not holding together, rather than the thread itself coming out of the fabric? That's what's causing it, if so. A fabric like this frays easily if you put that kind of pressure on the threads used to weave it right along the edge there where there aren't other threads holding them in.

The last photo is the clearest and I don't see anything obviously wrong there, but in the second to last and third to last photos, it looks like your fabric itself is coming undone. If that's not the issue, please describe the problem in more detail.

Are the threads themselves coming out? Is the stitch coming loose and you can pull out the whole thing of thread you just put in the fabric? Does the zig-zag look the same on both sides (not all bunched up on one side)? Are the stitches loose at all, or does the tension seem okay? Where is it coming loose from -- the ends where you backstitched it, or somewhere n the middle, or all over?

It's a little hard to tell from the photos, but are you sewing right at the edge of the fabric? That won't work in most cases, you need a seam allowance on both sides so that the seam won't come apart if the fabric frays. For a standard seam, line the fabric pieces up with the outsides facing each other, then sew at least 1/4" away from the edge (If you're using a pattern, most of them assume a 5/8" allowance.) You can use a straight stitch for this; the zigzag is mostly for finishing edges and for sewing stretch fabrics.
