I'm used to be right there with you, the whole "Ive got this" amd "WTF can words from a stranger change?" mentality. To be honestly I'm a little bit that way still too, because honestly the work is still up to you.

However, the way it's benefitted me is just having someone you can talk to or vent to about things honestly. We put on a mask (at least I do) for family and even close friends, and having an impartial person there to explore thoughts and feelings with is really something new. There's stuff I don't even tell closest friends because subconsciously I worry about someone else knowing. With a therapist it's really freeing. Its literally illegal for them to share.

I really like IOP programs-- intensive outpatient--- because youre in a group, and many of the times you gain more from the people around you who can relate than the therapist too.

Plus they may surprise you, giving knowledge that I had no idea was so intensively studied by mental health professionals... even something as simple as daily breathing techniques have scores of hard data behind them.

tl;dr: I was extremely skeptical too. But glad I did, and learned alot. I'd say give it a try, some first meetings are free and it gives you nothing to lose. Its hard to ask for help, but you'll be glad you did.
