  • Bipolar Disorder is terrible, I have it at it is like one day I am supper energetic and then the next day I always feel depressed and always fell sad. It is like I am dying inside of myself waiting to even get a chance to be normal. One time, I was at school and in the middle of no where I start to cry for no reason. If I was yelling, I was crying or even talking loudly I start crying and it is awful.

  • High self esteem is seen. It is legitimately felt if the person is deserving.

    The person tries to perform best to abilities and gives up in mind seeing no way out of the situaltion. Feeling helpless is also because of being lonely. The person is tied up to line of action planned and has a planned way of behaving which is not random. So it is giving up because of feeling helpless and not because of not having ability.

    It is a pathetic situation which needs treatment and hope to recover.

    This is an unbiased observation of people having such symptoms.

  • My dad is bipolar type 2, his manic episodes were the worst. I found out it might genetic in my family (almost everyone on his side is bipolar) and I have never been able to take medication because they were worried that It would make me end up like him.

  • It's a great feeling that after so much trial and error with meds, I'm finally on the right mix at the right dose and am not experiencing symptoms.
    Praying to my Father in Heaven to rescue me helped too.

  • There are days that I'm very confident with myself. My mind is very positive about almost everything and I feel very happy. I love to talk during these days. I joke around with my family and there are days that I feel very insecure. I would hate myself so much and would prefer to be alone and sleep all day. I get irritated with the smallest thing and i end up fighting with my parents. The highs are not as extreme as the lows though.

    Is this bipolar or is this just normal? I don't want to be self proclaimed bipolar just because its trending :c

  • I heard of tbis term recently, not knowing the full meaning. I've also been experiencing periodic depressive episodes, usually at night, and sometimes self confidence. I'm not sure if this is really bipolar disorder, but I would like to bring it up to my parents at some point.

  • i never visited a therapist yet. but what scares me is not the lowest points i get when i start self-harming and i want nothing but to die, what scares me is that sometimes i get extremely and inexplicably high moods. so high that i feel like im drunk, i cant stop talking, my heart is pounding, i feel like i can do anything and im too excited without even any reason. and then it falls apart without any reason. and then it repeats over and over again. i'm not sure if i do have a bipolar and i dont want to self-diagnose. but it scares me so much

  • I think my ex has this together with other stuff like narcissism and obsessive episodes, I tried so hard for so long, but nothing ever worked. He needs psychological help but he refuses to acknowledge that he has mental problems. Once even my therapist that I was seeing because I started getting so mentally and emotionally drained told him he has several problems and he needs treatment, but he just got offended and angry. This illness really sucks the life and joy out of a person and it’s very hard for their loved ones too. Praying for everyone with mental problems🙏🏼
