There are a lot of types.
I went for online therapy because of what I feel is a valid, though admittedly racist reason. At first it's awkward. You're sitting with this guy who's supposed to help you, and the only way for him to do that is if you completely open up to him.
This is another reason I went online: this guy has no leverage where I live. This is both good and bad, admittedly. He can't give me antidepressants.
Point is, the first date is going to be awkward as fuck. You will probably need to repeat your first date with a bunch of people because a good chunk are absolute dicks. A bit of advice - go for somebody about 40-45 years old. The old ones think they're masters of psychology.
Second, it's absolutely not what you expect even after you're made aware it's not like the movies. You're not going to lay on an expensive couch and lament. Your therapist turns into a sort of friend who you have weekly meetings, and you also barf money at him.
Seriously, 180$, and that's AFTER the site calculated I'm worthy for the "improvised cripple discount".
I think the trickiest part is figuring out what's good for you. I can't handle women, for example. I will lock up, and it doesn't matter if it's Emma Watson, or if it's a Karen from Walmart. The obese one.
I ended up with a fatherly guy, and he fulfills my needs for... fuck me if I know what. Well, among them is probably a fatherly figure that accepts I see suicide as an option. We talk about the weirdest shit, too. One second I'm rambling about neurology and various scanners, suddenly his kid pops up (the kid is like 5, mind you), and suddenly my dad mode turns out. I don't even have children! I sometimes wonder if he uses his kid as a therapy tool on me.
Also, he doesn't seem to mind me and the kid are having talks about suicide. The fucking kid is 5 years old!
He probably IS using his kid on me, now that I think about it.
So yeah... therapy... It's not like sex. When it's good, it's great. When it's not, go find a different therapist.
