Further to my esteemed colleague's points, PINEAPPLEBELONGSONPIZZA:
Personal History
I have known many people, in and outside of the CF, who have had crappy childhoods and/or relationships/marriages, in a couple of cases exhibiting self-harm for short periods. I have also known one who had absolutely disgusting, unimaginable, and completely unacceptable experience in the CF (I was her Assisting Officer; she ultimately prevailed). I honestly do not know how they maintained their sanity and continued to function, other than sheer determination. At least one is still dealing with her past several decades later, but put herself through university and earned a Master's degree while raising children with no support from her spouse.
Your background is not normal, but, sadly, far too frequent. If others can overcome similar obstacles, there is no reason why you cannot either. You can also turn your negative experiences into strength for others' benefit. Understanding abuse, neglect, and depression etcetera directly and dealing with it successfully can be of great help to others. That is why the previously-mentioned woman who earned her Master's degree is now a social worker.
Chances of Enrollment
You will never know, and nobody here can predict with any meaningful accuracy, what your chances are. You will have to actually apply and go through the whole process in order to find out. That aside, I see no specific reason why you should be denied entry. You will have to work hard on yourself to overcome the issues which have troubled and continue to trouble you, and which may spring up again many years after you think that you've beaten them down. You seem perfectly aware of this already.
"It's all pregnancy related". Maybe. Your past may have made you more susceptible, too. You have most likely already taken that into consideration, but it needs to be said. Military life can add some unique stressors that can inflame pre-existing problems, most especially when deployed or even long afterwards, but, as a Reservist, that is far less likely to happen.
Be aware of all of these things, and, when necessary, seek help before anything goes too far. There is more available now, and much less stigma. Any of us who has been in for a few years, and some with far less time in, has lost a friend and colleague (or several) to suicide, so we are fairly sensitive to that.
This is a supportive Site, and there are people who can help, either publicly or privately, if needed. There is also much discussion in older threads on this Site, so, please, explore those when toddler(s) permit.
Communication Style
Readability is important. If you wish people to read what you take the time and trouble to write, you need to take a little more time and trouble to make it easily readable, as well as clear and complete. Most/many will just pass on by when they see a massive block of words. I almost did, but decided to read it only because of BeyondTheNow's response - she is worth reading and her advice is solid.
There is seldom a need to rush a post out. I understand your fatigue and distraction, and presume that you had these thoughts composed in your head right then and wanted to set them down while they were fresh. I sometimes do that off-Site, when composing a lengthy reply or one that requires some research, in Word Perfect (because I despise Word). I can then work and re-work my composition until satisfied with it, and paste it back into the thread in which I am commenting.
One can also save one's effort during the process; I have put too much time into too many responses only to lose them due to a computer/software/Site glitch - and that is extremely frustrating.
Accuracy, Brevity, and Clarity (ABC, obviously) are the fundamentals of effective communication, and a requirement for military communication. Inaccurate communication can result in confusion, loss of valuable and often irreplaceable equipment, loss of lives, mission failure, and deep personal embarrassment. Overly-long communication (as this one may have become some time ago) can induce people to become bored, tune out, fall asleep, or begin plotting the speaker's/author's grisly death. Lack of clarity leads to misinterpretation, followed by the same effects stemming from lack of accuracy, or delay while further clarification is being sought.
Proper spelling, grammar, punctuation, capitalization, and structure are important ABC supporters, and help to make reading easier and more pleasant.
Just as the CF in general insists upon this, so do we on this Site (although, admittedly, nobody's died or been maimed by a confusing post here).
Conclusion (Finally)
Continue to participate here, benefit from the experiences of others, and contribute where you feel competent and comfortable to do so.
And, when the time is right, apply.
Qapla.
