Relationship Issues & Anxiety

I really hope that Ill be able to remain on this app, after seeing so many other people.. Theres so much kindness and happiness that I really need in my life. Lately Ive gotten very comfortable with my anxiety, its been around ALOT since September 2018, after my breakup. I started to really sit and think about life. My biggest fear is death.. so Im like 200% not considering suicide, even though I think today is my lowest point. My current boyfriend, I love him because he introduced me to this less serious side of life. But our problems come from his lack of ability to communicate and not having a back bone, weve talked... we came to a solution and hes been somewhat acting very good. Its been like a complete 180. Thats good for anybody... but it worries me, not necessarily because Im suspicious, but because of my anxiety. It will never allow everything to be okay. Eventually, it will come up with something.. I just want to get to a point with my anxiety that I can deal with again because Im so unhappy and its not even his fault all the time. A lot of my happiness comes from the people around me.. but I need to learn to be happy ALONE. Because these lonely nights, these times where its just me, plus my anxiety (that I have to deal w/ in MY OWN mind) are inevitable, like a lot of things I worry about
