all normal!
Sounds all normal to me! All relationships go up and down...and having a bit of depression does not help...but I does not mean it will hurt either!
I would suggest finding someone to talk to...I personally like to talk to professional strangers (as opposed to close friends) when I get down like that. It just makes it easier to open up and not worry about if you say something that might ruin a friendship...then once you have said everything out loud it is easier to filter what is said to who in your close-knit network of loved ones.
I recently asked my primary medical provider for a reference to a therapist...and was quite happy with who I saw! I chose not to use insurance because I ran into "mental health" issues when finding a new insurance once...but there were many other factors involved. Sometimes you can find a Family Help Center that will adjust your fee according to your financial situation. I would suggest thinking twice before taking any prescriptions...I am not saying they are wrong!!! I just know that the times I have seen therapists they all want to prescribe something right away and all I really needed was someone to talk to! I came to that conclusion after about 4 visits with each phase of depression.
Also...when/if you choose to see a therapist: listen to your heart! If you don't like talking to the person...move on and find someone else! Remember YOU are paying them to listen and you are by NO means obligated to go back if you do not want to.
I watched a movie yesterday...it was religious but you could take any of that out and just listen to the concept without the bible references and get alot out of it (I do NOT by any means want to make this a religious discussion...just wanted to point out that you could look beyond the religious part and follow the steps regardless it has gotta make a difference!)
The movie is called: Fireproof My Marriage
I have been a horrible wife lately and did some of these things (before I knew about it) and it has made quite a difference in our marriage. Neither one of us are perfect, in fact he still has some quirks that drive me crazy but the good parts far out-way how loud he eats!!! 
{{{hug}}} now go get to gettin' happy again! And don't hesitate to come here...I have and always walk away feeling like I got some great advice...or at least something to think about!!!
I am a nobody; nobody is perfect, and therefore I am perfect.
