<human>: I'm going to try to make this pretty short.

So, I've been talking with this girl Mackenzie for like six weeks. We met on Tinder and hit it off really well. She lives only two hours away from me, which is a distance I'm definitely willing to drive in order to have us meet up. Thus far into us talking, we have both told each other "I like you" and have talked about progressing into dating once we see each other in person, assuming things go well. 

To bring you to today: Twice while I've been talking to Mackenzie she's gotten really bad at texting back/talking to me. I generally am kind of sensitive to this type of thing so I tried to figure out what was going on both times. This most recent time, she disclosed to me that she doesn't think she deserves someone like me. She said that her self-esteem is very low, which is something I gathered about her, and that when she gets like this that she tries to make herself stop liking people. 

I really feel strongly for her and I really want this to work. I feel so sad that we both like each other but that we're having issues because she doesn't feel like she deserves a relationship or deserves to be happy. I know I can't fix her mindset, and I understand her low self-esteem and depression - I'm just here because I need advice as to what I can do next, if anything. 

I don't want to lose her and I still would love for us to at least try to be together, but I also don't want to pressure her or make her feel poorly about herself. I'm very unsure as to what I can do in this situation and I need your help.

Can you summarize the given text in a few sentences?
<bot>: talking to girl, we both like each other, but she doesn't think she deserves me and it's driving us apart. what do i do?
