Hi @cvb81, I just want to let you know that I understand how you feel and I can completely relate as I'm having a very similar experience. I feel like I'm in that same boat with you, so you're not alone.
Up until 2019, I had only been diagnosed with mild depression twice - in 1996 and in 2016. Both episodes were brief and seemd to resolve after I resigned from the job I was doing. Although I've only been diagnosed twice, I can now see many more times in my life where depression crept in. I'd feel sorry for myself for a day or two then put my big girl undies on and get on with enjoying life.
I was diagnosed with anxiety and depression in July 2019. I felt like it had fnally caught up with me, after all these years, and I wasn't going to be able to dodge it this time. Then, six months ago, I was diagnosed with BPD... at the age of 45. I completely agree with the diagnosis, which has been devastating because I really thought I was doing okay at life. But, I can now clearly see the trail of destruction this disorder has left in every aspect of my life. It turned everything I thought I knew about myself and my life on its head and I feel more lost than I ever have. I wish I never found out that I have BPD because I haven't felt anywhere near as empty or lonely in the last 35+ years as I have in the last 6 months.
My only source of support is my husband. However, he has unmanaged anxiety and, in my opinion, poor communication skills so, more often than not, his actions and words end up being a trigger for me. I've stopped talking with him about certain things because, after a number of heat-of-the-moment, but deeply hurtful, insults from him, I just don't feel safe sharing my feelings with him anymore, making this rollercoaster ride incredibly lonely. It has been a relief to find so many others who share similar experiences so I hope my story helps you find comfort in knowing that you're not alone.
