Hi, Loana. Welcome.
Wow. It sure sounds like you had a call to be supermom and were able to give it a good go for a little while. Many of us I'm sure wonder if we could shine in such a situation. Just being able to cope would satisfy me. Congratulations for making it through college!
Two things stand out in your post: The changes occuring during and around your pregnancy, and your much reduced quality of life now, without meds.
Unfortunately we can't be 22 or so forever. We can't be pregnant forever, nor is every pregnancy the same as the others. You came off your meds suddenly, and a quick withdrawal like that usually causes changes, oftentimes accompanied by a high, followed by a deep low. In the middle of that though there were the hormonal changes that your pregnancy and the post-partum period brought, and there's a likely chance that your pregnancy thus influenced your situation. A pregnancy affects your body for about two years.
Your description of college days sounds difficult, but you made it through nevertheless. Awesome! The meds you were taking might not have been the ideal ones for you, but meds evolve and are improved. Seldom, if ever, is someone on the same exact ones for life without adjustment and substitutions.
As you describe in your post, when you hit your low, you isolated and your children's quality of life suffered, as did your own. That is worrisome and for your sake and for the sake of everyone in your family, I urge you to seek expert medical opinion again.
Perhaps it might be a more productive thing to take meds again. None of us on the board here knows this. That's why I would urge you to find a good therapist and discuss this thoroughly. Sometimes people have to shop around a little to find one they feel comfortable with. Your past experience need not be your future one. Some people do take meds for life, and accepting that one is "better off with meds than without" may be a hard admission to make, but oftentimes it's just the smart and sensible thing to do instead of "just" working on modifying behaviors. All med plans can and must be reviewed regularly, so once on a med does not necessarily mean it's for life.
For starters though, have you taken the free Anxiety Test? (See link to i
