i need advice i’m scared to get drunk and feel like i want to act on my thoughts i just can’t do this i don’t wanna have this party anymore i’m so sad

has anyone experienced this or have any advice on what to do. okay so my senior prom is today and i’m in a long distance relationship so im going alone with friends and there’s an after party at someone’s house and it’s just your basic high school party with drinking and everything and ive never been to one but i wanna go with my female friends (im also a girl btw) but i have an rocd fear of cheating or something if i go. ive only ever gotten drunk once and all i was thinking abt was my boyfriend so i don’t understand the cheating “because you were drunk” thing. if i go to this party i do wanna drink a little but im just scared cause im overthinking that something will happen even though i would never do that. i haven’t asked my boyfriend about it yet as he’s at work but i am just not sure what to do.

I’ve been in a really difficult situation recently and this weekend I’ve been looking forward to for ages. I had a concert and then nights out planned with my cousins. But I’m a tad bit older than them and they’re a lot closer in ages, as are all their friends from uni, so I’m kinda just stuck here with nothing to do. They’re off flirting with people their age and dancing and I’m getting no attraction or even attention (not in an attention seeking kinda way just an I’m lonely kinda way). At the concert they left my 5 or 6 times to go to the toilet and get drinks, when I went to the toilet I went alone. I was left alone to the point people around started to notice and I had one guy say “left alone are you? You need to get better friends” I just feel very left out. I’m a lot older than them and I know I have to keep a mature head but I’ve already fallen into a pit of depression recently and very very low self esteem to the point I barely wanna go out in public, that I’m now sat here all anxious and in a really bad mood. I don’t even know exactly why or when it changed but last night I just snapped. My sister was off meeting new people, my cousin was dancing with creepy men, a guy I found attractive was more interested in my cousin, she started dancing all provocative on him and I was just kinda there. I then had people asking me if I was neurodivergent and bisexual which just sent my ocd spiralling and nobody quite understands how horrible it is to be in my head. There was this lovely guy saying how amazing stunning and beautiful I was but it kinda just made me go “you’re saying that because you feel bad for me, because you know they’re getting all the attention and I’m this ugly duff person on the side”, it’s insanely exhausting. I’m tired of it now. I don’t wanna be in a mood anymore but I can’t seem to shift it, I’m stuck

Two years ago, I went to a concert of my favorite artist. I listened to this artist every single day and was super excited to go, even though I saw him numerous times to that point. I went with some friends and my now ex-boyfriend. Admittedly, I drank WAY too much. I do not recall the last hour of the concert (I do not drink anymore). Of course, my OCD ran with this and for two years, I have been worried I did something awful that I do not remember, like hurt someone, etc. Since the concert, I barely listen to the artist because it causes me so much anxiety. I am supposed to go to a concert tomorrow for this artist, but I am terrified to go because I am worried I will be recognized as the drunk girl who kept requesting songs or if I did do something awful at the last concert. I really do not know what to do. What would your advice be?
