am i bi/polar

So first of all my relationship with my kids dad just ended which has devastated me. He has custody of my boys and i have custody of my daughter so our family is getting split up. so for the first few months of us getting back together after being apart for 6 years everything seemed perfect like we were in love. We always spent time together as a family. he came home every night after work we had sex everynight then about a month ago he started a new job and made friends and wanted us to go to a barbecue every week over there which I agreed but when we went I noticed everyone was getting drunk and we are in recovery so im sure you understand that if your an alcoholic you cant just control your drinking or just have one you gotta sustain from everything. Well the first time they offered him liquor he said no but then the next time when were there he drank behind my back and from that day on everyday.He stopped showing me affection and started going to there house like everyday while id be home with the kids. I told him I didint think it was good for us to hangout there considering no one there was clean and sober but he didint care. Its like he stopped caring about us. Then one night his friend held me in his room and was trying to block me from leaving and I told my man but he didint believe me. So I took my daughter and left but he wouldn't let me take my son with me home which I though was best since he was smashed. So I ended it with him. What really suck is were all living with my parents till the end of the monthi want to spend as much time with my boys as i can before they move.when he moves into a house with the boys but me and my daughter will have no where to go so im working on that. But its so hard for me to even be around him. My insecurities ruined our relationship and pushed him away to. Ok so for along time now not often but once in awhile I start thinking people are trying to hurt me and everyones out to get me sometimes ill just pack all my stuff and leave i know its crazy I hate having these thoughts well Ive been thinking this way for the last week and that hes in on it. Ive been super emotional for awhile now, irritable, angry,sad,and today getting the stupid thought that im dying from some cancer or disease the doctors have missed. Ive been tested for so many things which have all been negative the only positive has been a very high rheuatoid factor so I was diagnosed with ra and have been on plaquenil for it. I also take adderall xr 30 mg 1 time a day its the only way i feel motivated to do anything. So Ive lost tons of weight in the last month and had diarehea for a month now I weighed 162 2 months ago now im at 133. and i know its not the adderall cause ive been on it over a year. im so tired of living like this thinking theres something wrong with me or people are out to get me. feeling so sad like no one loves me. then other times ill just get lots of energy and start cleaning. Could I be bi-polar?or is this stress related? Please someone tell me what they think.....so lost and dont know where to go now with my life other than I have to do whats best for my daughter and provide for her

I think that in order to tell if you're bipolar, you have to look at how you thought/felt BEFORE you started going through all this with your husband. It's normal to kind of have a temporary insanity (for lack of a better term) after something life changing like that happens. .
