2 weeks

Its been 2 weeks since my violent outburst. I have been feeling more positive over the last week. The person i love and want to spend my life with has wanted to spend some time with me. Its good :)except i dunno how to prove i can change. I keep snapping coz i feel so upset, not because of anger, but he doesn't seem to see it like that.  I think he thinks im just a big angry ball of mess that will just explode no matter what the situation or the person. I  dont feel angry right now, i need to overcome being upset first to start tackling the real main issue my "anger"  If anyone out there has any suggestions about how to control all these emotions more easily please feel free to message me. I would be grateful for anyones advice.
