So, i've been dating this wonderful amazing girl for the past 3 and a half months, and we love eachother very much. The problem is my anxiety has been getting worse and worse. I have bad abandonment issues, and even though i trust her  that she won't leave me, i still get bad bad anxiety over it. Whenever she goes out (mind you, she went out 3 times in the last 4 months), my anxiety literally breaks me and i couldn't hide it anymore. Now she knowd about it and is very supportive, but i still feel ashamed and i don't want to be a burden to her. I trust her with my whole soul but i don't trust the people around her. Some people tried advancing on her put of course she shut them down, but she's very nice so it was kinda half i guess? Is there any other way i can try first before seeking professional help because i can't lose her over this god forsaken anxiety, even though she tells me we'll get through it together, i really don't want to burden her and limit her possibilities. 
Thank you all in advance!
