i can relate to how you are feeling right now. i am so sorry that you feel helpless and hopeless. it's such a lonely feeling.
in my case the answer to your question is absolutely YESLIFE CAN GET BETTER!!
i first ended up in a psych ward after so many trials of geting on the right meds and nothing seemed to work for any length of time. i was at the end of my rope. i felt like i was shrouded in darkness from within. i had no hope...no hope at all. it took 2 good docs and a lot of therapy after leaving the hospital, but i can tell you it was worth all the hard and sometimes painful work. i had to be totally honest with my pdocs cause i knew if i wasn't i'd fail again. they told me that i was responsible for my therapy and how it went. meaning if i went to an appt. and just fritzed around not telling them really how i was feeling, etc. i could expect the same results...nothing of value. i cried a lot, i was told to keep a journal i didn't want to do but did, i took my meds as prescribed, i called when i was out of whack, etc. the end result is i'm a healthier in the mind individual, i know i'm worthy of good things in my life, i know i may have not so good days but know now how to be proactive in my mental health, etc.
please know that i'm not gloating or bragging. your pain is real and mine was too. i have truly earned the right to the way i feel. death was the only option for me at the start. i could see no reason to continue. i know today there are GOOD reasons to live.
i hope you will find some meaningful things in what i've written. i will pray for you and hope you too will gain the happiness you deserve. what i'm striving to do is give you HOPE. even my good friends say i am a miracle!
