Veryunhappy,
I am in a very similar situation as you.
Though I have only been married for five years. After about a year he totally changed in about every way. Wont go into all the details but it was so disappointing for both me and my now 17 year old.
I started getting VERY depressed. Went on medication and lost most of my friends due to being so depressed, isolated, withdrawn. This has been the worst time of my life. I lost my job(due to a car accident)and have been looking for a job for three years now if you can believe that. I have a masters degree, (in social work, so it's almost useless). Because of the severity of the depression I went on disability so I make a
very little bit of money but not enough to rent an apartment for me and my kid. Not to mention the bills, food,ect I am stuck and see no way out. I do not have any family to go to.
There are good things about my husband. He is not abusive or anything, though he is constantly berating me about the medication, so I warn you, maybe you shouldn't tell him about what meds you are going on or the details about that area of your life-it may be used against you. Anyway it was for me.
I think about the future and it seems so bleak. So sad to think about living with someone who doesn't really care about or know me or listen to me, or remember anything that I say or care about. How can I look forward to this kind of future?
I see no way out, and like you, even if I get a job, here where I live in my profession, it pays so little it would be hard to make ends meet. I know people do it. Before I met him I had help from my family but that is all gone with no possibility of returning.
Not sure what to say as far as advise but I know how you feel. Please feel free to email me. I could use a friend.
