i feel so lost

i feel so lost and alone. i constantly get rejected by potential suitors, some even before we meet in person. the ones that i do meet in person seem to not be interested in me. i have been sort of lost since i lost my partner of two years about six months ago. i am trying to move on by meeting other people, and i have so much love to give in my heart, but it seems that no one wants it. i know "forever alone" is just an untrue adage, but i am beginning to feel like i'll never find anyone that i am attracted to that understands and accepts me for who i am. i am diagnosed bipolar and borderline, and sometimes i take my issues with myself out on people that have nothing to do with it, making my relationships unstable. not to mention jealousy and reassurance issues. i admit that it's probably hard to love me, but i am trying to change by going to therapy and CBT. i feel like neither is helping me with the longing feeling of wanting to share myself with. i feel like i'm not worthy enough to better myself for myself, i feel like i can only move forward with my life if i have someone to work for. it's hard to get motivated, so i am pretty stagnant in my life at this point in time. i don't know what to do, so i've turned here for some insight. i hope that there's more to say in response to "keep busy" and "stop looking". thanks for your time :]
