<human>: Can you provide a brief overview of the text?

I've (M, 24) been dating my girlfriend for almost 4 months now, (it's both our first serious relationship) and I really really care about her and think she is amazing, but lately i've been quite unhappy with our relationship. 

First of all, I wanna say I suffer from clincical anxiety and depression, fairly mild but still enough to clearly affect my mood, and I get lonely quite often. So, whenever my gf is in town (she travels a lot, for about 2-5 days on end), I always try to make plans to see her, which we usually do. But for me, i'd really like to see her more than once a week. I understand she has friends that she wants to hang out with, and I allow her time to do that, but she never invites me to do anything if any single one of her friends is involved, and I feel like she doesn't really WANT me to be around if that makes any sense.

Idk, maybe i'm letting my loneliness get the best of me, but I'm not sure if I should confront her about it, or let it be and try and focus more on myself (it's a struggle). Any advice would be greatly appreciated, and let me know if you'd like more clarification that I could provide on the situation.
<bot>: I'm unsure whether i'm being too clingy to my girlfriend or whether I have a clear case to say she is not treating me how I would like.
