Hell, woman, there is no such thing as "overreactive" or "too sensitive". Humans are supposed to cry and yell and lash out when they're upset. Just watch babies and children- they give free vent to their emotions all the time, until the adults train them not to. It's a form of honesty; trying to hold back tears or anger is bad for your soul. Just try to feel the rest of it- love, happiness, hope- just as intensely as you do the bad stuff.
Now, you already know this part, but nobody else here does:
Years ago, sometime in the late 80's, I was at your jw family's house and got talking to you. I don't remember how it came up, but some mention was made of treatment for mental health problems. In the lamest j-dub way imaginable, I said something to the effect of "well, if they just trusted in Jehovah, they wouldn't need these doctors!" Looking back on that day, I'm amazed you didn't smack me! You were cool, though. You quoted some study you'd read that found that witnesses have the highest incidence of mental health problems of any religion. I was skeptical to say the least; it sounded like Satan was making you slander the organization, to lead me astray! You said lots of sensible things over the years, but this turned out to be the crucial one.
I filed it away under "questionable apostate misinformation" and continued on being a dub. Eventually, still a dub but dating a terrific worldly man (who is now my partner), I started learning to use a computer and internet search engines. Not knowing what else to type in one night, I typed Jehovah's Witness mental health into google or yahoo. And up popped a list of websites- freeminds, virushead.net, silent lambs, etc. After some initial panic (Eeek! Apostate lies!!) I actually read what they had to say.
Long story short, I'm no longer a witness, but my relationship with the Divine is deeper than ever. I didn't break up with my man, as the elders told me I had to, and marry a witness guy who'd keep me submissive and pregnant; my partner and I are now into our 5th year together. Instead of pioneering to trap more people in that sorry excuse for a religion, I went to college to better myself and the world I live in. Instead of cleaning the hall on Saturdays, I'm doing charity work to help children and animals. I helped my mom free herself from the borg, and I'm working on rescuing my brother and his family now.
So next time you feel down on yourself, just think of the effect your words and actions have had on this planet. In a very real sense, you saved my life, and I will always be grateful to you for that. Your brothers and sister all know how much you love them, and they love you right back, even when your emotions get hold of you. Don't doubt for a minute that, whatever the next life turns out to be, you'll see your brother again, and he'll be rewarded for all the good things he's done in his life; so will you. You'll be in my prayers tonight, and I send love and blessings to you, and peace and comfort to your brother.
