I once went to some sort of therapist for issues with food addiction. When I saw she weighed about 400 lbs herself, I absolutely never went back. I am not judging her for having a weight problem, but yes I do judge people who pretend they know what they are talking about and can help you when it is SO OBVIOUS they don't know how to help themselves with the same problems.
As far as my food addiction, I struggled through on my own but came to a full realization that I would have to live with preplanned controlled portions and calories the rest of my life if I wanted to be free of food obsession and also be at a normal weight. I am a Weight Watchers Life member but I don't think it matters what program you follow as much as the very deep realization this is "forever" not for a few weeks until I reach a goal, or until I have a bad day and I just have to overeat to cope. I have been maintaining an 80+ pound loss for many many years.
Like so many experiences in my life, the overweight psychiatrist was one more example in my head that even when their own problems are not so obvious, it is just as likely as not the therapist has similar problems and cannot solve them for him or herself, let alone others. I have had other bad experiences with them. My XH was some sort of sex addict who had been with more prostitutes than he could ever hope to count. After one session, he came home and told me the therapist told him to first see whether I might be agreeable to an open marriage! Obviously, he never went back.
My DS hated school and because of some issues that really elevated when he was 15, I took him to a therapist. They tried to put him on meds for depression. The shrink said, "It will make you feel better." He was a bit of a smart alec and said, "So will smoking pot so should I do that?" This was around 2004 and there was not the talk of it being harmless or legalized then and this shrink was in the mindset of that was a horrible illegal drug that would lead to other drugs, but ADs are fine (I personally believe ADS are highly over prescribed and that people should find more natural ways to "feel better" than taking concoctions of chemicals that alter mental states, and do all sorts of other potentially harmful things to your body but hey you "feel better" so it is fine. I don't think they are better for you than pot. DS's sense of humor flew right over her head and she went on and on about how bad pot and "drugs" are for you.
Then the psychologist who would not be directly prescribing the drugs called me to talk about reconsidering having him work with the drug prescribing one. He told me DS is depressed and it causes him to do poorly and be unhappy in school. I told him DS was the happiest kid you would ever see on weekends and vacations when there is no school and nobody is talking about school. Of course I'm just a mom and educator, what do I know? So no, he didn't go back to the shrinks either. They were worthless, I'm sorry to say. I homeschooled him the next year, no more depression! Wow! Maybe that would be a solution for some but not everyone in the circumstance. Even so, the "problem" they should have worked on was helping him learn to cope better and perform better with public school expectations, get along better with kids, etc. It never occurred to them to look for the actual problem and work on it. Just assume "depression" and meds.
When my H cheated on me and my step-DD died in 2006, yes I went to see a therapist and she was okay. I went to her more as "paid friend" to confide in, somebody who did not know my H, much the way I used this forum. Not to give me advice or tell me what to do, just to talk to. If she "advised" me what to do, I would not have kept going back. I've mentioned it here several times over the years, I don't take advice and I rarely give advice. I like to hear others' experiences and share my own. I learn from that and it helps me make decisions, but no, I don't want direct advice.
Now I'll get off that soapbox for a bit and say that you might find one who could help with the parenting skills issues because I think that is an issue that is better defined and more likely treatable through following a plan that a family therapist might recommend. Good luck!
