i have recently broken up with my first real girlfriend (we dated for a year). I worked third shift and communication started to falter and in the end it was to much. Prom is one week out (I am one year graduated and she is a senior in high school). Before breaking up we decided to give eachother some space and after 4 days I went to her house out of concern (she has anxiety and depression and the last time we talked she was showing symptoms of going into an episode) it was there where we talked and I found out that in those for days I had been replaced as her prom date (by he ex who had dumped her by calling her a “toy”) and that we had basically broken up. 

After a lot of crying (from both of us) we decided to give it another shot. That lasted for two days before she decided to break it off again (senioritis mixed with anxiety inducing an existential crisis) so she could find herself. I did my best to understand and support her while being incredibly hurt. We agreed we would keep talking and be friends mostly because we’ve only ever talked to eachother about our problems. She has depression and anxiety. I hear voices and have recently been having panic attacks (including an ear splitting ringing at the base of my skull that causes debilitating pain. 

Last night, after a really rough day dealing with my family I was on my way to work when I asked if I could stop by my gfs (this term is used for clarity as if I changed what I referred to her as everytime it changed through the story it would cause confusion) for some moral support. She. Informed me that she was on a walk around town but I was drive by we’re she was anyway. Long story short I’m ashamed (I cannot express how much) to say that I drove around the area looking for her when she texted me expressing that she didn’t want to see me right now for fear of falling back into our relationship and ignoring my calls. 

I spent my night at work crying (luckily I work mostly alone and no one saw)

im so ashamed 

we had a long talk this morning and part of that talk was me coming here 

We've decided to remain friends and hat we both needed a lot of time to work on ourselves. But she was still going to take her ex (from before me, who a few months after they broke up rejoined our friend group) to prom. This hurt me a great deal. In the last two days I’ve lost five pounds due to a lack of eating (I feel like I’m going to vomit constantly). We’ve been talking and now she’s taking me...too. Beyond that she insists that I eat dinner separate from them (all of this hurts me in the way you would expect) right now we’re talking about it but I don’t know what to do.  

To to add to problems I love her and can’t hurt her

my family was already pissed when they found out about the other guy after the break and wanted me to break up with her but I couldn’t. 

If if they find out that she’s taking someone else to prom with or without me, then I’ll be judged/mocked/subjected to “support”

her main complaint that I didn’t take her out enough. Which is true, probably once every week or too. But in fairness we’re broke teenagers who both work and she’s in school. She never made an effort to talk about it before requesting a break. 

Ive heard of people’s depression driving them to act out (either for attention or just to feel something) and this feels like that in my gut

for the people who will suggest that she’s just trying to break up with me. I don’t think this is he case (could be wishful thinking) because most attempts at reconciliation have been made by her and I keep giving her outs (for instance talking on her porch so she could just go inside if she didn’t want to talk)

i really would just like some advice and I’m sorry if I’m posting this in the wrong place or am being insensitive to anyone

thanks in advance
