What now?!

I don't know where to start. I will try and make it short.
I went to see a doctor about 2 or 3 years ago as I felt I was finally ready to get help. I was given sertraline/zoloft and was pretty much sent on my way. After a while of being on it I was given citalopram instead (zoloft didn't do anything), and was given a number to call so I could arrange seeing a psychologist. I went to see her for a consultation and the appointment was a little disappointing, we discussed one of my issues to do with body image but she seemed to ignore my other problems like depression and anxiety. I was put on the waiting list after this appointment and I am still on it. I will go along to the appointment when I get it but I do not feel like it will help me at all. All she offered me was everything I already knew.

I had been suffering anxiety and what not for years but started feeling really positive, I made changes, felt pretty good (not cured but good). that lasted a few months short of a year and now suddenly I am completely depressed.
My doctor is not bothered. I try to make an appointment and get told I can not be seen without a phone consultation but don't get one till the next day(when I miss it). He just gives me meds and sends me on my way.
I has been difficult the past few weeks and a lot of things have happened. It is too much to deal with and I start thinking about harming myself or even killing myself (suicide is not something I have planned). I want to talk to someone and feel like I am not worthless. I am just back where I started but with less hope and more depression.

I would insist on trying different medication. It took me a while(2 years)to find the right combination but now I rarely have a bad day. It does take time to see if a medication works but not that long. Maybe there are exceptions I don't know about. Sometimes one medication won't help much and another will work wonders.

I am going to try med meds. I don't think meds is the only thing I need. I want to try meds but also talk to someone. But I don't think I am getting the advice I need from this psychologist, I have been suffering from these problems for years and she spoke as if my problem was minor. She told me to "go to collage" and didn't listen to me when I told her I dropped collage twice because it became to much. I can hardly leave my house.
I have to on the waiting list for appointment that is not going to help me.
It is nice to know i may find medication that helps me though.
