I didn't want to go out and socialize no matter how positive I sounded when my dad died.

Well sometimes I thought I did but usually resulted in hating the experience I as ended up feeling overwhelmed, like the pressure was on to remain upbeat and positive whilst out.

Best support I got from my bff and bf was when one of them showed up at my house with food and movie in tow....

I'm not saying you should just show up at her house randomly, idk if you 2 even have that type of relationship, but staying in might be worth suggesting as opposed to going out.
