"Have I been gaining weight because I'm depressed, or have I been depressed because I'm gaining weight?"

From what I know, people lose or gain weight as a consequence to them being depressed and changing their eating habits. Depending on whether or not you were eating healthily in the past, you might be having self-esteem issues and anxiety that might cause depression. Usually, the first option ends up being the right one and you might not realize a change of habits until you really look at it because you're so focused on how you're feeling. Best wishes :)

It could be either of the two but more likely to gain weight because when depressed its difficult to get up and do physical activities

In my experience it is a cycle. One thing feeds another. Depression, however, works differently on different people, but nevertheless wether you are gaining or losing the weight it is something that takes courage, strength and to break out of. The days you manage to break the self hatred and apathy are the ones that bring you closer to become healthy in every way again!

This is the chicken or the egg argument and you should focus on what you think is causing your depression, if it is only the weight gain that is making you depressed, then I guess that would be the right answer, but if it something else that you feel is causing you depression, then the answer would be you're gaining because you're depressed.

It depends if you gained weight before you where depressed or not, I suggest eating more fruit and getting full with that and limit the junk you eat :)

The only one that can answer that is you, and it depends on the circumstances, actually. If you've been depressed and binge eating or if you're weight conscious, well it could be both.

Neither. Depression doesnt really mean that you gain weight just because. Your eating habits and active time has a lot more to do with your weight then depression

It might be none of the above. You might be gaining weight because of an underactive thyroid. There are many reasons. You should speak with your doctor.

No matter which one came first, you can work to solve them both together. Surrounding yourself with good friends and family is key, as they will improve your depression and can help you work towards solutions to losing th weight you gained.

It might not be one causing the other. You might be eating more because of your mental health, and that may cause your mental state to decline. Or, it may be the other way round. Either way, the best way to deal with it is to not be hard on yourself.
