I did see that you were looking, I'm really glad it's financially doable for you right now. It's hard to say how much it will cost (I am on my mom's health insurance until I graduate, so I get a very decent rate.... the last therapist I saw only required a $15 co-pay, but she was also my School Psychologist, didn't have her Ph.D., and frankly, didn't help me all that much). I wouldn't have gone to her, but I found her on a website... it was a lot easier than looking through the yellow pages of a phone book. This page
isn't loading for me right now, but I am pretty sure it's what I used to locate her information. Definitely use some kind of online source because it will list basically everything you need to know about that person and what they specialize in... you don't want to end up having to pay a hundred bucks for someone whose specialties are completely apart from what you need.
(The page loaded and it is what I ended up using, I really recommend it)
The thing I didn't like about therapists is sometimes I just wanted to talk about what I wanted to talk about, because I felt like I had soooo much inside of me I haven't said to anyone. So, it's really important to find someone who can benefit you in ways they are trained.
If you are concerned with co-dependency still, it might be a good idea to find someone who is a Marriage and Family counselor. They see individuals as well as couples and families and know a lot more about relationships than anyone could ever tell you. My reservation with that is that they'd focus on what went wrong in your relationship and less about you as an individual, but it's about finding the right person. Some therapists are stepping stones to other therapists, so you could always start there and then ask for recommendations when you feel that you have gotten what you needed from that person.
The best thing to do before going into your first appointment is to write down the things you want to address. If you do this then you have control over what you need to work on and don't have to worry about the conversation veering off as often as it will. In my therapy sessions I often let the therapist take control and then I don't particularly feel like I've gotten anything good out of it. Also, your first session will be very very draining, so be prepared for that. They'll ask you every last detail about your childhood before they can touch on anything that is happening in the present, so don't feel discouraged, they're just getting to know you.
Payments is really hard to say. It will depend on who you find or what type of insurance you have (the website I sent you to actually tells you what kind of insurance they accept) and if you don't have any, the best thing to do is call and talk to the receptionist. I'm not precisely sure where you live but I typed in the city you listed on facebook, and I see a couple results that look pretty good. I'll send you the link to a couple people that look good and maybe they will be close enough to where you live that you could set something up. There's lots of social workers and clinical psychiatrists on that site, so it's a process of weeding through what is right.
I hope that helped a little! I know more from my own experience than I do from my education, but I'm more than happy to share the chunk I learned!
