So much loss I don't really know what to do anymore

Kayyyy
After loosing the love of my life in 2011 and meeting someone new in 2013 that I love so much then going through a miscarriage in early 2015 and struggling since then to save my relationship I'm just exhausted mentally I'm. It expecting any sympathy I know we all go through hard times but I finally ended my relationship and asked him to move out and ever since I've felt better so I know I made the right choice but I'm heartbroken because I truly don't know how I will ever open up again. Does anyone have any success story's or advice for me I sure could use it
