My impression is that therapists generally try not to have social media connections with their clients. Everybody needs time off from work, to take care of personal stuff or just relax and have fun. If a T is constantly reading posts or tweets from clients, they don't get that time off and then they burn out and aren't as good in session.

So your T would probably not read your Twitter feed much, if at all. Chances are you will post something that you think is important, he will not respond (probably won't see it), and you will get very upset and feel rejected and ignored.

Truth is you need to accept that this T is available to you only in sessions, he is not thinking about you 24-7. If you need comfort or to talk between sessions, can you reach out to someone else? A friend, a family member?
