Therapist, psychologist, psychiatrist, and support group experience over here.
Psychiatrists: Absolutely worthless unless you want drugs. These people are only here to diagnose you and recommend drugs. They do not actually care about your problems outside how they convert to symptoms. If you do not want drugs, avoid at all costs.
Psychologists: In my opinion, hit or miss. Some are ******** amazing. Others also have the ability to prescribe meds and decide that they really, really,
really want you on them, despite how often you say you don't want to be on them. I went to one psychologist for an in-depth psych eval recently and half the meeting was literally her trying to put me back on drugs when I explained many times that they make my situation worse because I can't take them daily. I could talk more about this but I don't want to have a ridiculously long post.
Therapists: Also hit or miss. When a psychologist hits, they hit AMAZINGLY and you won't even know wtf they did, but you'll be getting better. Therapists can do the same thing, but when they miss, they miss HARD. You can get therapists with some pretty whacked out views who can actually make your situation worse. This is especially true if you are a minor and your parents don't agree with you. Technically the same thing can happen with psychologists, but
usually psychologists have a lot more, uh, pride or something. Not sure how to explain.
I've never had a good experience with a psychiatrist. I've had good experiences with therapists and psychologists. There was a time I was on meds and went to a psychiatrist pretty often. I had 2 different ones. One was an a*****e, the other one was pretending to be a therapist and really was no help. If you're on drugs, get the drugs, but meh. Psychologists who can prescribe meds are able to respect your drug choices (or non-choices) but there is the possibility they won't.
A good psychologist and/or therapist will have you leaving the appointment thinking all you did was talk and "not get anywhere" on a normal day. Other days you'll definitely know you did good. But if you are leaving meetings thinking that the psych/therapist voiced an opinion of some sort that didn't really jive with you, that's probably a relationship you should reconsider.
I was in therapy for 6 months and we saw eachother once a week. Pretty dedicated. 80% of the visits were me talking about how I didn't think I needed therapy and the visits were a waste of time because I was mentally healthy. I eventually stopped therapy and about 3 months later I finally realized....
Therapy is a preventative medicine. And those "We're not accomplishing anything here" meetings were actually VERY GOOD meetings. I am now trying to get a new therapist.
Support groups can be helpful but also can make things worse. I went to a couple PFLAG
meetings, and my problems were just not anywhere close to other people's. Support groups are great resources-- they can hook you up with all sorts of things. Recommendations to therapists, doctors, etc. Great reading material you can give to others or read yourself in regard to whatever issue the support group is about. But the actual group meetings have been overall negative in my experience. Everyone just vents about their days, and if your problems aren't similar, then you feel singled out and feel bad. Worse, if you are having worse problems then everyone else, everyone else just looks like they're complaining for little/no reason.
Some support groups also have cliques and a lot of drama.
Some support groups are great, but I'd say most (at least on the GLBTQ spectrum of support groups) are just not worth it outside their resources.
Family therapy can be good but normally ends up bombing in my opinion. Most people who are in family therapy are there because some one (usually a parent) is an obnoxious a*****e. And being in family therapy does not change that. I've been to family therapy once or twice because of my brother's problems, and it sort of worked out but only because it was more of a "teaching parents how to parent a violent ADHD kid" sort of thing.
Some people have obviously had family therapy work for them, but on the whole, it usually doesn't, especially if you're a teenager and you have shitty parents. What is more advantageous is if your parents and you attend the same therapist at different times, so the therapist can speak to you both privately.
I'm probably missing a lot of stuff. I could seriously talk about this sort of thing forever, probably. But my post is already huge so I'll just stop here.
