My experience of dealing with my GP was not as positive as those upthread.
At the start of this year I went in because I felt pretty low and desperate. I couldn't sleep and everything seemed on top of me. I am considered by everyone to be a 'coper' but I felt utterly overwhelmed, especially with work.
I was signed off for 2 weeks, and just the break from work really helped. She said I didn't need medication but referred me for a session on CBT and then 6 sessions of group therapy through MIND, which I found really helpful.
BUT (there's always a but) the group therapy was in the eves (I work FT and couldn't go to any daytime meetings) so whilst I did enjoy going, it didn't help with the feelings of being overwhelmed and having no time for anything!
I went back to my GP about 6 weeks ago as I was feeling really stressed, struggling to sleep (again) and I had a constant tightness in my chest. I've previously been investigated for high blood pressure so I was concerned about that.
And she basically told me to go away, do some of the techniques I'd learned in therapy, that I couldn't expect any time off (I'd not gone in to be signed off...in fact those 2 weeks were the only time I've ever been signed off in 20+ years of work!) and I didn't need medication.
I'm still not quite right. I cannot cope with the volume of tasks I have at work (for example this week I am off today, working remotely on 2 other days - 1 of which is a full day of meetings at one office, the other is a full day of presentations at another, and yet by Friday I also have to put together a several thousand word publication). Sigh. Oh, and I failed my driving test today. Possibly, or even probably due to nerves, but I feel my GP will not be prepared to offer any solutions.
To be honest the main thing that would help me is having a job that was less bloody ridiculous in terms of expectations (or at least paid a crazy salary so it was worthwhile!). I'm working on that one.
Apologies for the essay. Hope it all goes well OP.
