Unsure if synthroid dose is enough anymore

Hi

I am new here with this being my first post. I was diagnosed with post partum hypothyroidism two years ago after my second child turned 3 months old along with PPD. I knew something was up, but really didn't know what. What was strange is that I was borderline hyperthyroid and then next month that all switched. Since then I haven't really given it much thought. I really don't know if the dose I have been given is working or not. My blood tests all come back in the normal range and I get them checked at least every 4 to 5 months.

I have gone back to the doctor a few times complaining of not being able to remember things easily, like putting my milk in the pantry instead of the fridge. I realize it as I am doing it, but it is frustrating and time consuming when it does happen. I will go into a room and completely forget why I did two seconds later. Or I will tell my kids or husband I will do something for them like get a drink or a snack and two minutes later they are reminding me that they asked for something. My doctor dismissed that as being a busy mom and I felt pretty foolish going in to find that out.

For the longest while I have been completely exhausted. It doesn't matter how much or how little sleep I get, I feel the same tired feeling every day. I am tired all-the-time!! By mid morning to mid afternoon I am so tired I can barely sit in front of my computer to work. I work from home so naps are a daily occurrence however it is certainly affecting my job performance. I will only take a 20 minute nap, but some days I have to take a longer on or even have two naps in between jobs. Plus I have zero concentration. I mean I am here instead of working right now. I can get about 10 minutes of work in and then my brain wants me to do something else whether it is getting up to do the dishes, pick up toys, or just surfing the net.

I am also having these mood swings I would guess you would call it. I can be happy and excited one minute and a few hours later I am so frustrated and angry at anyone. There are a few times where I just had to stop what I was doing and go upstairs to my room so I could be by myself. Even my husband coming in to check on me made me frustrated. I get angry quickly at my kids and yell when I really shouldn't. I hate that.

Anyways, that is what I have and my husband has noticed lately. I am on 0.05mg of synthroid but even though my blood tests come back in the normal range, I believe that is a pretty low dose. When I was diagnosed the doctors really didn't explain how this would all affect me other than I would be on medication probably the rest of my life.

So my question to you is...are these signs of hypothyroidism or depression? How can I tell the difference? Should I go to my doctor and be persistent?

Thanks For replying. I think that the doctor is checking all areas of the thyroid blood tests. I am not entirely sure of the numbers however I made an appointment for this Friday so I will know more then.

To answer the questions, this was all done through OB and family doctor. Other than having two ultrasounds on my thyroid, I have not gone to an endocrinologist. And this could very well be symptoms of depression as well but I am also on anti-depressants and have been put on them the exact same time at synthroid so I have two medications and I am not entirely sure which one isn't working, or what is going on since I feel so in the dark about hypothyroidism.

I had my second child, three months later was told I had hypothyroidism then some PPD and after that moved across country to be closer to family, had to find a new family doctor and that is why I feel like it has all just been dumped on me and not really explained. Hoping to read through the posts here to get some understanding.
