TT vs donk, open ended

[Kimpan]

How do I play this?
we are 138BB, I don't want to raise and get it in on this flop since I will be behind if I do. Calling would be without odds and probably wont get paid if I hit my straight. He is very tight preflop so his range is probably JJ+ AK, AQ. Should I feel weak by folding this?
