<human>: Can you succinctly summarize the text in 1-3 sentences?

So, obviously I am embarrassed about this issue (see u/). That probably is a related issue. 

Anyway, this might not even be the correct sub for this question, but I figure it's a fine place to start.

The crux of the problem is that I have bad anxiety/insecurity when I don't hear from my SO. It's not all the time, mind you, but often enough that I am hurting. I have had this my whole life, I suppose. These feelings of insecurity. And I recall having them with my two previous GFs, though they were short lived (~4months per). And I didn't notify them of these feelings, as I haven't really notified my current GF of these feelings. I feel like she shouldn't have to change her laid back lifestyle in which she is not attached to her phone. She doesn't have a smart phone, and doesn't want one. 

So there's the "intro." I guess to add I would say that I mostly want to know what I can do to make these feelings go away, because just talking myself through an hour or so of unanswered texts is pretty rough at times. I *know* she isn't cheating on me, but for some reason I still feel insecure when she doesn't respond to my texts. 

Basically I know that I am in the wrong, and being an insecure little b*****. I have been trying to work these feelings out on my own because I don't want to make her constantly be on the phone to 'let me know' what she is up to so I am not worried about whatever. I'm not even sure what I am worried about. Maybe that she doesn't love me as much as I love her, definitely an aspect of me not feeling worthy of this blissful feeling of being with her. 

I've considered counseling, but don't have that money or time to really do it. Though I am about to change situations and can probably afford it, so if that is the suggestion I will look into it. I hoped to fix this on my own, but after 4 yrs I think I may have some underlying issues that need working out.
<bot>: Have feelings of insecurity and neediness towards my GF in really stupid things. She doesn't know. I have tried self-fixing, not gone very far. Any advice?
