is it bad that I feel this way?

Lately I've been just not feeling like myself I have suffered from anxiety most of my life lately I just been in this mood where I feel like no one wants me and no one wants to be around me. So I have had this best friend for about 6 years and lately she's been hanging out with other people she always gets in to trouble and I try to help her and give advice and be a good friend. I try to text her but she never text me I've been having a hard time in school stressed out and I haven't heard from her in like 2 weeks. I feel like she doesn't want to be bothered with me anymore and it sucks like I'm going through school and I have no one to really talk to about my problems
