I'd like to tell you that it gets easier with time. I'm not sure that it does though. I think it does become more manageable. Have you spoke to your doctor? Trust and believe that many people are going through this. Maybe some in your own circle of family and friends. As Weaver pointed out people are reluctant to talk about it due to the stigma associated with MHD. YOU ARE NOT ALONE.
Yes, I've definitely felt like that before. And I felt like that for a really long time. It does make it really hard to connect with others, but I think what worked for me in the past was being really open with my partner and family. It helped them know what was going on, and while it may have taken a while for them to 'sort of' get it, I think it's worth the effort. They might never understand what it actually feels like, but sympathy is better than neither empathy or sympathy. Also, they might understand or at least sympathize more than you 'think'. I feel like when I was depressed, I basically felt completely isolated -- but it actually wasn't the case at all. Our perceptions change with our moods, I hope it gets better for you.
Just know that you can work through it, even though it may take time, and that while you may feel like they don't understand you, there are a lot of people out there who know how you feel and can relate.
Simple answer, yes. I have found maintaining relationships very hard, luckily my wife sees something in me that is alwvays there. It 's hard to say if I am an introvert or extrovert, depends on the day. My shifting moods and mental ability make me feel very alone. I have recently taken a leap of faith. I told my client that I am bipolar, she is also a friend, I am remodeling her bathroom. I had a severe cycle right when I started the job, so I disappeared. I opened up about what was happening to me and she was very receptive, empathetic really. I tried to manage opiate addiction alone to no avail. I finally started talking about it, I'm trying that with bipolar now. Trying to act like everyone else has been feeding my isolation. I am attempting to admit who I am to myself and those in my life. I don't feel so alone, so far. I hope this doesn't backfire, there is a lot of stigma around this disorder, and some don't get it at all. I figured I couldn't feel much more alone, so I am trying to be open and honest about my situation. I'll let you know how it goes, though my stress seems lower already. I am focused on finding my own balance, not fitting in. At least know that I relate, you are not alone, no matter how you feel.
