Breakup

So last week my boyfriend and I broke up, it was a mutual decision and we both agreed that the relationship wasn’t working anymore. We both care for each other deeply, and it was a very hard decision to make. I know deep down that it was the right thing to do, but I just feel so depressed and it feels like I’ll never recover from this. I don’t have a huge support system like he does, and from what I’ve seen he’s been keeping himself pretty busy every day. All I’ve been doing is laying in bed and feeling like shit. I know this hurt him as much as it hurt me, but I just don’t get how he gets up and out in the morning, cause I really don’t have that energy at all… we agreed to take three weeks without contact before we figure out the rest (we own a house together). But does anyone have any advice to how I can cope a bit better, and maybe give me some uplifting words? cause I really feel like I’m never going to be happy again. Thanks!
