Well, glad that you came here to vent. Right now I'm pretty OK. Subject to change, of course.
Its real hard to try and talk to the family, and sorry guys, especially men. I think its because they have heard of hormones, but never had PMS, PMDD, been pregnant, or had post-partum depression. They just don't understand moods.
When I feel like you I call it misery. Mixed up inside, it could be a real happy time but something is eating at me too. Nothing I can pin down. Uncomfortable in my skin.
Therapy does take awhile, they have to get to know you, and you them, and figure out what to address first. Thats why you need to put some thought into it before you go in and write some things down. What's the thing you want to tackle first? You can identify for yourself that you are suffering from anxiety, jumpy, nervous. You can tell her that right out, instead of describing it for most of your session (as I have done ) and then the session is over, with not much feedback. And that's what you're paying for, professional feedback. You can vent here or anywhere you can find a kind ear. But I found that I just hated myself on the way home from the appt if I had blabbered uncontrollably. Sometimes you can't help it when you "strike a nerve" and that is good, don't get me wrong.
When you have no one to talk to, try journalling. Believe me, if the family doesn't want to hear about it, they sure aren't going to look for your journal ! I used to be afraid to put things down in black and white. The nice thing is now we have computers, so we can FLY !
Considering all the surgeries and sickness you have had to deal with, I would say no wonder you feel that way. You say you are on Cymbalta and Trazadone, for how long? Maybe you aren't at the max dose, or need to be switched. Maybe it something else going on in your bod. Sometimes they aren't as effective as they seemed at first, needs to be "tweaked". Call the pdoc. You must be on thyroid meds too, I don't know, but maybe they need adjustment.
Also, on the internet, if you are so inclined, you can Google self-help for anxiety. In the meantime. No miracles, but maybe an idea or two.
Hope you get some relief soon.
