I dont know what to do

Hi i am 28yrs, have a good job, good salary. Its been 4years i am all alone because i was built up that way, but this december i had a new boss who is married, he approached me and gave compliments. He grabbed my attention will all his words and it kept going on until last few weeks he kept going on and off, last friday we made out the next day he blocked me with no reason, now i feel so betrayed because he knew i have anxiety issues, i just dont know what to do becauae all these things are new to me and its very difficult to come out. I am trying at the end i feel like i am loosing hope, i feel lost, i kept reminding myself things are better than this but i keep failing, now all i think about is to just die. I have do have supportive friends and parents, i feel like becauze of my mood swings i am hurting everyone around me. I dont deserve this i feel lost i feel like running away. I just dont know what to do. Its hurtful that i got used and tricked into the trap easily.
