[Final advice] How should I come out to my crush ?

Hello guys, it's-a me again, I've come once more to seek some final help with my crush, Well I already made a post several days ago ( http://ift.tt/2khefm5) And now I need some advice to come out to my crush, or somehow tell him I love him.tl;dr of the last post: I [20M] met a guy [21M] 4 months ago at my uni, I don't know his orientation, never really talked about girls or anything and he seems kinda touchy with me (sometimes like to quickly stroke my hair), we text alot (5-6 k messages on, with a lot of emojis). He came over my place 2-3 times to spend the afternoon with me. Last wednesday I suggested to see each other, he agreed and we both had luch at my uni and then come over my place, we spent the full afternoon together, a bit tipsy, watching videos, playing, joking. Point is I didnt tell him how I feel yet, and I'd like to.Okay after that (long) tl;dr here's the news: Before leaving my appartment, he suggested we meet again soon, during the afternoon or even the evening at my place, with some alcohol, I agreed. I later texted him "thank you for this amazing afternnon" in which he replied "We had so much fun ^ ^ we could do better next time, there's so much trips to have :D"I plan to ask him if he wanna come to my appartment next week or in 2 weeks. But thing is, I don't know if I should tell him when he's there or tell him by texting that i'm in love with him. I fear the unsettling situation in my place where he says "Yeah, no, thanks, but I have to go now", I also fear, with texting that he never replies to me (I dunno if he would do so).That aside, I also need to tell you that i'm very prone to severe anxiety and depression; In he last two months, I barely cried every night because of that, i'm always in a bad mood, exhausted (but not when i'm with him), and I don't know what to do, I plan to go to a psychologist if everything goes wrong, but i'm too afraid.I've always been too afraid...I've already wrote something on a notepad to express my feelings: I don't know if I should send him this messages now, or wait a bit more..(Here's some sentences (translated from french, so I kinda apologize if it's not relevant):"It's been 4 months we know each other, and since the beginning, I saw a great friendship growing between us[...] But problem is, behind that happy face I wear everytime I see you, I'm still a weak and depressed men;This mood which appeared 2 months ago, after I realized I wasnt only appreciating you...Yeah, this amity I had changed to love; a corrosive love that slowly kills me, and makes me suffocating.[...] Time goes on and so does my heart, dying a bit more each day with the will of spending those with you,I'm just controled by this sickly obsession that wants to know about a somehow reciprocityAnd that took my heart and mind in hostage because he never felt something that powerful before.And i'm so sorry about that...[...] I apologize if I upsetted you, shocked or even disappointed you with my story,And that I get you involved with my emotions,But I somehow believed, for a momentThat we could live happily together")I need some help...
