Sounds like you are having very rough times. I feel for you.
A lot of good things have been said, but I wanted to add my 2 cents, having experienced some hormonal crash and mess ups myself, mainly due to my own making, by going on a rather extreme autoimmune elimination GAPS, with very little carbs.
I am not gonna go into all the details, but I had a full thyroid crash, amenorrhea for seven months, a mood problem, a brain problem, energy problem, athletic performance problem etc. etc.
What I can say, is that getting back in order takes time. It took me about a year, with very hard work to get back to "normal". For some, it might take longer. There are no easy fixes. Being "strict Paleo" is not a guarantee for anything. In fact, if you are doing low carb, my might mess up your hormones further. People are different though. But for me, low carb was very bad, but I am not claiming this is the case for everyone.
For me, eating more carbs in the form of fruit, was essential to getting better. I make a big effort to get 200 grams of carbs per day, a bit more when I train hard. I eat fruit 5 times a day, and I drink OJ. I take a table spoon of coconut sugar or honey on hard work out days. Starches have not been all that good for me. Fruit is better. If you crave, eat!
I was also on the pill for 16 years, and I think it set the stage for the hormonal crash I had last year. I do not think you do yourself any favours by going back. In the medium and long term you are making it worse, possibly much worse.
I think I saw in another post that you had had some ED related issues. What I can say is, do not be so hard on yourself when you are trying to fix your hormones. Allow your body to gain some weight if this is what it takes. In the period I got better, I gained 5.5 kg in a very short time in the form of muscles, water and some fat. It might not sound like much, but it was over 10% of my bodyweight. I was not so happy with the fat gain in my thighs (I already had a pronounced pear shape) as I compete in triathlons, and I like to be as lean as possible. Luckily my coach said all the right things: That the weight gain was a part of getting my health and hormones back in order. That I looked good. That I had gotten stronger, and that it is difficult to get to stronger without adding some fat. That I should continue to focus on my health and hormone balance, and that the leanness should be a long-term issue that will come by itself, but not something I should focus on in the short and medium term.
Another thing - the period when I decided that I had to re-think my approach (after 6 months on the Perfect Health Diet, and 8 months on Paleo), I cut virtually all training for six weeks. This was very hard for me, as I had a race coming up 3 months later, but I think it was the right decision. It seems like you train pretty hard. Maybe you need to wait untill your hormones are more balanced.
Eating more frequent meals was also critical for me to get better. On a Perfect Health Diet I ate 3 times per day, and tried to get a 12 hour overnight fast, sometimes 14 hours. Now, I eat 5-6 meals per day. I know this is quite common easy fix for women with hormonal mess-ups. A friend of mine is able to control extremely nasty PMS depression by simply eating frequent meals.
I try to get nutrients from foods - bone broth every day, raw diary when I can get my hands on it, otherwise organic goats milk and goats cheese, liver once per week, oysters once per week, mussels, prawns, white fish, oxtail and lots and lots of tropical fruits. I found that eating minimal vegetables work better for me. I used to eat tons of sweet potatoes while trying to fix my problems, but no more. I take desiccated thyroid, and as of recently, a low dose of pregnenalone. Desiccated thyroid worked for me, even though my TSH and T4 were consistently normal (T3 low after low carb stint).
When I stated with 35 mg pregnenolone a few weeks back the effects were pretty instant. I was already feeling 80% "normal", and the pregnenolone gave me the last 20% back, in terms of brain function, mood, and recovery from workouts.
And one more thing - for me charting my cycles (after my period came back....) using FAM has been helpful. It indicates that I still have an estrogen-progesterone problem, but at least it seems to get slowly better.
Good luck. Everybody is different, so you just need to find out what works for you.
