Reduction of isolation is something that can happen regardless if you return to work or not, and it can even start today.
I have to say the support services here in Ireland are pretty scant. Socialising in Ireland basically means the pub and lots of alcohol which even I know is a bad idea for me.
It's wise to know that one environment isn't right for you.
What about volunteering? Another option is to look into social, book club, educational, or volunteering groups on meetup.com or other resources in your area. The more simple and small the next steps, the more successful you will likely be. It will feel uncomfortable and it will feel like it is increasing anxiety at times. But keep taking small steps and reach out here.
I'm a bit new to all this. I've posted on the forums before but not been very coherent. I will set about socialising more and reduce my isolation now that I understand things how things work. May I ask the people who do some part time work if they inform the employer beforehand of your PTSD?
I first started with volunteering. Some places I said I had PTSD, some I said I had a disability, and at some places, I said nothing at all. When working, it depends if I am asking for an accommodation or not, and the laws and the system in the US is different than here. In the US, I am not required to reveal the disability if I need an accommodation, but I do have to have a doctors note verifying I do have a disability that requires the accommodation I'm asking for. This is what I prefer, and what seems to work the best for me right now. I did tell two employers when the PTSD was going to impact how I carried out my job, and I risked telling these two employers because they were very unlikely to stigmatize me for it. Otherwise, I haven't generally told employers that my disability is PTSD.
Now I understand why my T was pushing me to do some part time work. Sadly I don't see the therapist anymore. Haven't been in therapy since 2008. I was in great shape after the therapy but I gradually and slowly isolated myself more and more and then the agoraphobia began which led to more isolation. I got my GP to prescribe me anti depressants and these in conjunction with the anti psychotics that my T got me are quite nice. I was even described by someone as "quite pleasant" (who didn't know I even had PTSD) which I hadn't heard for many a year.
I'm glad that both therapy and medications have been helpful for you. It's great that you have even had positive feedback from someone about the changes since the medications were added in. Have you considered returning to therapy? Are there barriers (like cost, availability) that make it hard?
