Sick and tired of this

They tell me my heart is fine and blood work is okay, well, why do it feel like I can't breathe out of nowhere like there is a blockage some where feet swollen at times where it feels like no circulation is getting to them with full blown pressure on my head to the point Iam grabbing it in pain. Stressed to the max and then I find out my no good cousin whom I made the mistake years ago of taking around my still boyfriend started talking to him, and just basically went behind my back and slept with him. Me thinking it was over forgave the situation never received apology from either one of them , come to find out her weak self mental wise still with him so called eloped and just had a baby by him. The pain resurfaced these girl cousins I've nothing to do with these days and haven't for years in fact I want to delete them off facebook, me trying to be the bigger person and except their request they always did ish behind my back and had to have what I had. Not being funny are overly stuck on myself, but Iam the prettiest one and they are no where near good basically messy and worldly.
I don't want the dude back been over that years ago even when he was with her, and tried getting back with me I never ever allowed it just the thought disgust me some lines one should never cross ever and they've crossed way to many ,have caused me nothing but pain and never apologized for any of it and thats what hurts the most. And I will never have anything to do with her or their family in anyway again, sad when so called family brings you down quicker than strangers I would've never went so low. How do I heal from this I need therapy for all this until then I come to where I know I want be judged, to get this out because keeping it inside has caused much anger and resentment mixed with bitterness for people. If own so called family keep hurtting me with no care in the world who do I trust basically nobody, because they've made that hard not just them but a few others and I just want peace and things like this to stop messing up my progress with anxiety management any advice?

Dawn, there is something I need to tell you about "most" young men,
they play a game with girls and young women, called "you cant tell
when I'm lying", they use good girls and women for a score card to
brag about to their buddies, like a game, they act like no one gets
hurt, but we know all to well that there are broker hearts laying in the
dirt of their sin everywhere. People are not animal's they have hearts
and soles for some irresponsible little brat to smash a Ladys heart and
sole is a Mortal Sin, always I am here for you, Peace

Thanks everyone it is hard to cope with and my mother always stress to me to be bigger and better, I've tried and yes taken the higher road going on a healing path where I must except there can never be any communication between any of us again. Because I want nothing to do with them and for a while I felt I was wrong for that, but understand that Iam not and must protect what sainty I've left and stay far away for it is better that way. Thanks for always being there to inspire me, and Merrida so sorry that happened to you ,I wish people had hearts like ours that are unselfish and cared about other people feelings and the damage that can be done. But I've faith complete healing will take place for both of us sooner than later, until then I keep on praying for better days and happy days full of more happiness for all that has ever been betrayed by so called family.
And SC if you can post the link it will be greatly appreciated.
