Low mood linked to relationship?

[Earlgrey19]

I’ve been feeling low and struggling with sleep for a while. My GP has suggested antidepressants. I’m finding myself very preoccupied with negatives of my marriage at the moment (though none are dreadful, mostly just to do with tension and DH being very rigid and defensive, and it doesn’t help that he is pretty stressed). The thing is, I can’t quite figure if I’m just depressed and that’s affecting how I think about DH, or if the marriage itself is making me feel low (or is a major contributor, at least). At times I’m even wondering if I want to separate (though have two very young DC). But I’m wondering, if I go on antidepressants will the relationship/my feelings about it improve? Or will I put myself through side effects when my marriage is the problem. Has anyone any insight from their experience?

Can you

pills wont help a bad relationship.
personally i'd spend more time self reflecting as to why your depressed?

You would probably get insightful posters in chat or relationships.
I do suffer with MH issues mainly around PMS there are months I despise DP though I keep it to myself as I know how great helpful kind and understanding he is when my hormones aren't raging.
It doesn't stop my mad thoughts thinking I want out.

Thanks, I know it’s hard to reply to my post not knowing the circumstances. I’ve had a tough few years with a major family trauma plus a bereavement. Things are better but it’s possible I’m depleted from all of that. I’ve had quite a lot of psychotherapy, but feeling lower now. Marriage came under huge strain after all that we went through - and with young DC; over the last year it has improved but still not easy. On waiting list for Relate (though DH doesn’t want to go).

And I have SAD

Did you have depression prior to your marriage?

Umm, not really though I’ve probably always been prone to being a low. Then again I’ve been through of lot of difficult circs in last few years: my youngest dc had major health problems and nearly didn’t survive, and I lost one of my parents around the same time...

a bit low
